Sight is one of the five senses we use to understand and explore our surroundings. We need it to function and react, and when sight is compromised, issues begin to surface.
You cant read a book. You may not be able to distinguish one thing from another. You could even injure yourself, for example, if you missed seeing a stairstep.
Glasses and contacts are great options to improve vision as well as LASIK. The pros and cons of LASIK should be determined before electing to do it. It is a type of surgery after all.
If you are struggling with seeing clearly, LASIK surgery will help sharpen your vision.
Getting the 20/20 vision you have always desired can be done without having to rely on contacts or glasses.
Correcting Vision Problems
Our eyes work a lot like a camera in the sense it focuses light in order to make an image. Light is focused and bent to properly refract that image.
Vision problems happen when there is an issue with refracting that light. It will leave people unable to see things clearly that are close or far away from them. Images are less visible when the lens or cornea of the eye itself is distorted too.
Ordinarily, people used glasses and contacts to treat these eye problems. Now, there is another choice: LASIK surgery.
LASIK is able to improve sight directly by enhancing the focusing refractive power of your eye. In order to do this, corneal tissue is removed in a controlled, precise manner through the use of a special laser. The laser helps to reshape the cornea back to normal to fix the refractive error.
There are a few things to take into account with LASIK surgery. It is elective and so you should be prepared to pay for the surgery out-of-pocket. Vision may be blurry right after the surgery and you might feel drowsy from the lingering effects of medication. Ensure that you have an arranged trip back home afterward.
Pros and Cons of Lasik Surgery
Thoughts such as “is LASIK eye surgery a good idea?” come to mind for many people. As with any invasive surgery, there are risks you must weigh alongside the benefits.
Are there more pros than cons? Are you willing to accept the potential unwanted outcomes? Are the negatives associated with the surgery minor or deadly?
Building a list of the benefits of LASIK surgery and comparing it to a list of why you should not get the surgery will help decide if it’s the right choice.
Pros
It is Simple and Fast: If downtime after surgery worries you because you can’t afford to miss work or other events, you can rest easy. Lasik is an outpatient surgery done at a doctor’s office while you’re awake. There is no trip to the hospital needed because it is less invasive. You can be in and out in as quick as 15-30 minutes. Believe it or not, most of that time is simply preparation.
Quick Results: Most surgeries take several days to weeks to see results post-op, but not with LASIK. Most people notice a significant improvement in their vision right away.
Say Goodbye to Contacts and Glasses: Perfect Vision without needing glasses or contacts anymore is often the main benefit for most people. The worry of application is gone which is especially helpful for those who forget to grab their glasses. Dry, itchy, or red eyes associated with wearing contacts can be ended for good too.
Excellent Vision Recovery Rate: LASIK is meant to restore normal vision and it does this well. Over 90% of people who do the surgery no longer being near- or far-sighted. It has the same positive results for those who suffer from astigmatism.
Cons
There Is a Chance of Eye Injury: You must be certain you want the surgery because there is no reversal once you do it. This is fine in the sense it improves vision, but it’s concerning when damage to the eye occurs.
You May Require Lasik Later: While results are long-lasting, LASIK surgery is also by no means a permanent fix. The higher your prescription is before doing the surveys, the more you may notice a decline in vision as time passes. This is known as a condition called myopic regression.
It’s Not Permanent: The older we get, the more changes we notice and our eyes are no exception. The shape of your eyes alters as you age and LASIK can’t prevent that. Older adults often develop presbyopia and, sooner or later, may have to start using reading glasses to see.
Everyone is Not Qualified: If you want the surgery, it may either not work or do more harm than good to you. It should not be done of your cornea is uneven or thin or if you suffer from cataracts or glaucoma. It is not a good fit if you have an autoimmune disease or diabetes. Those under 18 and over 40 are not a good fit as well.
Fully Understanding the Complications: While the surgery is minor, it still has its risk. You may experience unwanted vision changes. You may experience starburst or double vision, halo eyes, light sensitivity, or severe astigmatism. Dry eyes may occur for as long as three months after the surgery. These outcomes are greater for those who may already be experiencing these issues. The chances you can make an existing problem worse is possible.
Should You Undergo Lasik Surgery?
After taking a look at the pros and cons of LASIK, many people still decide to undergo surgery as the greater outcome outweighs the risks. In fact, less than 0.5% of people who completed the surgery wound up with serious complications.
It is perfect for those who no longer want to be inclined to wearing glasses or contacts.
Nonetheless, it is a case-by-case situation and should be thoroughly thought through. For some the risks are small and worth it, for others, it’s enough to decide against it.

Leading 8 Drones in 2018
As the basic public's hunger for drones grows, so too does the large volume of choices available. The drone market has actually exploded in the previous couple of years, catering for everybody from those who just wish to fly something around the sky for fun to market specialists who use them to capture 4K aerial video without the need for a helicopter.
Below you'll find a choice of drones which we think about to be the very best ones readily available right now. We've included a large range of price alternatives as well, to cater for those shopping on a budget plan as well as deeper-pocketed people.
Prior to setting your hard-earned cash for one of these drones, it's a good idea to investigate what sort of policies exist in your specific region. Lots of nations need users of big drones to register them officially, so make certain you're in ownership of the truths before requiring to the skies to avoid any brushes with the law.
1. DJI Inspire 2
Possibly the finest flagship-level drone in presence today
Weight: 3440g|Controller: Yes|Video camera resolution: 30MP|Battery Size: 4280mAh|Range: 7 km
Incredible build quality
Excellent battery life
Plenty of features
Cost is high compared with more consumer-oriented drones
Soundly knocking its predecessor off the top spot is the extremely remarkable Inspire 2. With a sleek metal composite bodywork upgrade, it's a far more appealing piece of package. Whats more, with more innovative object avoidance innovation you do not need to fret about that stunning body getting scratched by you accidentally clipping a tree.
You get more than 25 minutes of flight time out of the twin-battery arrangement, and the ability to swap electronic camera lenses implies that expert photographers and videographers have complete control over their images and 5K video.
The fully-featured smartphone app and dedicated remote control make this drone extremely simple to manage, however make no mistake, this is a professional piece of package.
2. DJI Inspire 1
A professional drone with a professional rate tag
Weight: 2935g|Controller: Yes|Camera resolution: 12.76 M|Battery Size: 5700mAh|Range: 2 km
Incredible construct quality and piece de resistance
Modular style means it's easy to upgrade
Too expensive for the common customer
The DJI Inspire 1 might look like some sort of fearsome war-robot from the far future, once you've overcome its rather daunting look it's all too easy to fall for this agile and feature-rich device.
It comes with its own controller, which boasts remarkable range (you'll need to supply a monitor through your smartphone or tablet's screen, though), and the electronic camera-- which is mounted on a gimbal for aiming-- is upgradeable, so you do not have to stress over your investment ending up being obsolete after a few months.
Performance in the air is nothing except excellent, even in rather windy conditions. The DJI Inspire 1 is likewise incredibly swift and-- when twinned with that excellent controller-- easy to manoeuvre. It's just drawbacks are its expense and that the bundled battery only gives you around 15 to 20 minutes of flight time prior to it requires recharging.
3. DJI Phantom 4
Weight: 1380 g|Controller: Yes|Camera resolution: 12.4 MP|Battery Size:: 5,350 mAh|Variety: 3.1 miles
Nice and steady 4K video
Good and steady 4K video footage
Not as easily upgradeable as the DJI Inspire 1
A refinement of the already impressive DJI Phantom 3 Professional, the Phantom 4 brings with it a more sturdy building and construction, upgraded object-avoidance technology and-- like so a number of DJI's offerings-- an outstanding devoted remote control which connects to an equally feature-rich smart device app.
4K video recording is supported, and the gimbal design implies you get rock-steady video even when the drone is moving at speed and changing instructions. The greatest downer-- and you'll discover this is a typical grievance with many industrial drones-- is battery life, which is only around 15 to 20 minutes, depending on how difficult you're pushing the drone.
While it's not in the exact same league as its Inspire 1 sibling, the Phantom 4 provides a similar degree of performance and performance for a lower price, making it an exceptional alternative for fledgling aerial professional photographers rather than experienced specialists.
4. Parrot Bebop 2
Uses a new viewpoint on drone flying
Weight: 500g|Controller: Optional|Camera resolution: 14MP|Battery Size: 2700mAh|Variety: 300 metres
Fisheye lens enables shake-free video recording
Optional controller and headset are exceptional
Certain functions cost additional to unlock
The Bebop 2 is a mid-range offering which won't break the bank yet uses an unexpected quantity of functions for the cost. The electronic camera utilises a fisheye lens, and stabilization software application removes the requirement for a gimbal; integrated with the smart building of the chassis, which utilizes rubber dampeners to lower vibration in-flight, this leads to video footage that's refreshingly judder-free.
If you're feeling specifically flush you can take the Bebop 2 to the next level by acquiring the optional flight controller and FPV headset. The previous connects to your mobile phone and uses proper flight controls, while the latter uses your phone's screen to present a first-person view of exactly what the Bebop 2 is really seeing. It's initially quite disconcerting to fly the device in this fashion, however after a while you'll want all drones included such an accessory.
On the disadvantage, Parrot has actually locked away a few of the Bebop 2's more intriguing features, such as path preparation and 'follow me' performance, behind a paywall, which indicates the expense increases even more if you wish to utilize these. Battery life is likewise somewhat frustrating, so it might be worth buying an extra power cell.
5. DJI Glow
Small rate, smaller sized drone, with Jedi-like gestural controls
Weight: 300g|Controller: Yes/Not included|Electronic camera resolution: 12mp|Battery Size: 1480 mAh|Variety: 2 km
Controller-free gesture controls
Definitely small
Automatic Quickshot modes
Spotty W-Fi connection with smart devices
Brief flight time
Easily swayed by the wind
The DJI Glow is the business's most approachable drone. With its extremely cool gestural controls that make you seem like a Jedi and its different colored body shells, it's definitely more fun out of package than a lot of the others on this list.
It is quickly controlled using your mobile phone, however it deserves noting that that's the only controller you're going to have unless you elegant purchasing a separate controller. It's certainly economical in regards to drones, but still we want to have actually a controller included for good measure.
It's an incredibly light drone, unsurprisingly as it's the size of a can. This is both one of its biggest strengths and its biggest weak points as it's extremely simple to carry around in your bag, but will be affected by wind during flight.
6. DJI Mavic Pro
Weight: 734g|Controller: Yes|Camera resolution: 12.35 MP|Battery Size: 3830mAh|Range: 4.3 miles
Extremely portable
Committed remote control
Low-light image quality is disappointing
Until the DJI Spark occurred, the Mavic Pro was the tiniest drone in DJI's lineup, and includes folding arms so it can be stowed away in your bag. Don't let its small size fool you though-- this pint-sized leaflet boasts the sort of efficiency that DJI's larger drones are famous for.
The electronic camera is mounted on a gimbal, which is uncommon for drones of this size. It provides wonderful outcomes with both photos and video in excellent lighting, although the little size of the sensing unit means low-light shooting can sometimes be tricky. The Mavic Pro has a leading speed of around 40mph, so it's adept because department, and the battery benefits around 20 to 25 minutes of aerial action.
As holds true with other DJI drones, the Mavic Pro features a devoted remote control that utilizes your phone's display screen to show you precisely what the device is seeing. Variety is estimated as being over 4 miles, providing you the chance to capture some incredible stills and video without fretting about the connection dropping.
7. Xiro Xplorer V
Looks good in the air
Weight: 1202.02 g|Controller: Yes|Camera resolution: 14MP|Battery Size: 5200mAh
Eye-catching design
Good endurance
Fisheye lens introduces distortion
It's rare for a business to put the looks of its drone ahead of core performance, but the Xiro Xplorer V certainly looks special, specifically when it's up in the air. This gadget truly does look business thanks to its sharp edges, LED lighting and fetching camouflage color design. All this fits almost into a specifically created backpack, which is an optional extra however comes highly suggested.
Like the Parrot Bebop 2, the Xiro Xplorer V utilizes a fisheye lens to grab broad shots and capture steady video footage. Regretfully the execution of this lens isn't as remarkable as on Parrot's drone, and there's a fair bit of distortion towards the edges of the frame, especially throughout video recording.
That aside, the Xplorer V is recommended purchase, specifically when you consider that it's priced a little lower than some of its rivals. Battery life readies too, peaking at around 25 minutes per charge.
8. ZeroTech Dobby
A drone that's little enough to suit your pocket
Weight: 199g|Controller: No|Electronic camera resolution: 13MP|Battery Size: * 970mAh|Variety: 100 meters
Ultra-portable
Smart device app is feature-rich
Battery life is poor
This is the tiniest drone featured in this list, and also among the cheapest. Despite its modest status (and rather odd name) the Dobby is a surprisingly effective and versatile piece of kit. Pitched by ZeroTech as a 'selfie drone', it's little enough to fit in your bag, which offers it an advantage over many drones, which are often too large to be brought around quickly.
The small size of the Dobby implies it gets battered around in strong winds, however on a good day its performance is remarkable. It's managed via a mobile phone application and functions such as orbital moves, object tracking and facial acknowledgment are all included as standard, and are simple to execute. The drone's audio and visual sensors, repaired on its underside, suggest you can perform palm liftoffs and landings, and you can utilize it inside your home.
For such a little drone it need to come as not a surprise to learn that endurance is perhaps the most significant sticking point with the Dobby-- the battery lasts in between 5 and 10 minutes, depending on variables such as wind speed and recording time. Image and video quality are likewise a step down from a few of the more pricey drones on this list.

Pros /
Colorful, full-HD display; Long battery life; Plenty of ports and DVD drive; Accurate sound;
Cons /
Grainy webcam; Narrow viewing angles;
Verdict /
A colorful display, long battery life and strong build quality make the Aspire Aspire E 15 E5-575-33BM a fantastic value.
If you want a sub-$350 Windows laptop, you usually have to settle for a dull, low-res screen; lackluster design; and mediocre performance. For $349 ($429 with Windows Office), Acer’s Aspire E 15 E5-575-33BM defies those expectations, providing a colorful 1080p display, solid build quality and a reasonable Core i3 processor. Throw in over 8 hours of battery life, a DVD drive and just about every port you can imagine, and this 15.6-inch laptop is a real winner for consumers on a budget.
Design: Solid
Acer’s Aspire E 15 is made of sturdy black plastic with a dark gray, matte lid that has a subtle crosshatch pattern and texture, along with a deck that looks like faux brushed aluminum. The notebook seems to have solid build quality, because it didn’t creak or buckle during my use; the keyboard didn’t show any signs of flex while typing either.
At 10.2 x 1.5 x 1.2 inches and 5.06 pounds, the E 15 E5-575-33BM is bulky, but it’s not much bigger than other budget 15-inch laptops. The Dell Inspiron 15 5000 is heavier (5.2 pounds) but thinner (0.92 inches), while the HP Notebook 15-ba009dx (4.6 pounds, 0.96 inches thick) is both thinner and lighter. The 14-inch Asus VivoBook E403SA is a much smaller alternative, at 3.18 pounds and 0.7 inches thick.
Ports: Everything you need plus DVD
The Aspire’s thick frame leaves plenty of room for both a DVD writer and almost every conceivable port. The left side houses a full-size Ethernet port, two USB 3.0 connectors, HDMI-out, VGA-out and a USB Type-C 3.1 port that’s good for data but that can’t be used to charge the laptop. The right side contains the DVD drive, a third USB port and a 3.5mm audio jack. The front lip offers an SD card reader.
Keyboard and Touchpad: Comfy and accurate
The Acer E 15’s keyboard offers a good typing experience that’s free from any of the shallowness or flex we find on many budget laptops. The keys provide a full 1.5mm of vertical travel and require 64 grams of force to actuate, a combination which prevented me from bottoming out as I typed. I reached a strong 100 words. Many users will appreciate the dedicated numeric keypad, which makes using the calculator or editing spreadsheets easier.
The 4.2 x 3-inch buttonless touchpad provides reasonably-accurate navigation around the desktop, but its surface felt a little slippery to me. The pad seemed to have a little trouble with pinch-to-zoom, as it didn’t always respond right away when I performed the gesture in Chrome browser or Windows 10’s photo app. Three-finger swiping to switch between apps worked every time.
Display: Surprisingly good
It’s rare that you find a 1920 x 1080 display on a sub-$400 laptop, let alone a display that covers this much of the color gamut. The Aspire E 15’s 15.6-inch screen outputs at a sharp 1080p resolution with tones that are vibrant, though not always accurate, and very limited viewing angles. When I watched a trailer for Spider-Man: Homecoming, the reds and blues in Spidey’s costume popped, but appeared a bit oversaturated.
According to our colorimeter, the Acer E 15 can reproduce an impressive 159 percent of the sRGB color gamut, which is well above the 94 percent mainstream laptop average. That showing also trounces competitors in the E 15’s price range, such as the HP Notebook 15 (70 percent), Asus VivoBook E403SA (68 percent) and Dell Inspiron 15 5000 (72 percent).
Unfortunately, the numbers here don’t tell the full story, as the viewing angles were quite narrow. Dark images began inverting at just 45 degrees to the left or right.
Don’t try using this laptop in direct sunlight. The Aspire E 15 E5-575-33BM registered just 215 nits on our light meter, well below the 276-nit category average but actually better than showings by the Notebook 15 (174 nits) and VivoBook E403SA (201 nits). The Inspiron 15 5000 (213 nits) had a nearly identical score.
Audio: Decent
The Aspire E 15’s speakers offer output that’s quite accurate and loud enough to fill a medium-sized room. When I played Deep Purple’s “Smoke on the Water,” I could hear a clear separation of sound amid the drums, vocals and guitar. There was only a hint of tinniness in the high tones.
Performance: Ready for (light) multitasking
With its Core i3-7100U CPU, 4GB of RAM and 1TB 5,400-rpm hard drive, the Aspire E 15 E5-575-33BM offers just enough performance for light multitasking. With 12 tabs open in Chrome and a local 1080p video playing in another window, I experienced minimal lag when switching between the tabs. However, when one of the tabs was streaming a video (in addition to the local video) or downloading a large web page, things slowed down to the point that letters I typed in a Google doc didn’t appear until seconds after I hit the keys.
The Aspire E 15 scored a modest 5,408 on Geekbench 4, a synthetic benchmark that measures overall performance. That’s much less than the Core i5-7200U-powered Inspiron 15 5000’s score (6,742), but better than the showing by the HP Notebook 15-ba009dx (3,291) and its AMD A6-7310 CPU.
Acer’s laptop took 5 minutes and 14 seconds to complete the Laptop Spreadsheet Macro Test, in which we match 20,000 names with their addresses. That time is slower than the 4:01 category average and the Inspiron 15 5000’s time of 4:03, but more than twice as quick as the times from the Pentium N3700-powered Asus VivoBook E403SA (13:31) and the HP Notebook 15 (11:40).
The E 15’s 1TB hard drive copied 4.97GB of mixed-media files at a rate of 36.6 megabytes per second, which is significantly slower than the result for the Inspiron 15 5000 (83.4 MBps) and a bit lower than the HP Notebook 15-ba009dx’s showing (40 MBps), both of which have 5,400-rpm hard drives. The VivoBook E403SA and its eMMC memory did even worse (30.1 MBps).
You can watch full-HD movies on Acer’s laptop, but don’t think about playing anything more than casual games on it. The E 15’s Intel HD 620 GPU managed a mediocre 49,211 on 3DMark Ice Storm Unlimited, a synthetic graphics test. That mark is well below the Inspiron 15 5000’s score of 60,475 and the category average (86,474). However, the Notebook 15-ba009dx (33,649) and VivoBook E403SA (26,224) scored even lower.
Upgrading: Encouraged
Unlike many manufacturers, who don’t want you to touch your laptop’s innards, Acer actually cites the easy-to-remove upgrade panel on the bottom as a reason to buy this laptop. If you want to improve the performance of the E 15 E-575-33BM, you can upgrade its RAM and storage drive easily and inexpensively.
Once you take the panel off, you can put up to 32GB of DDR4 RAM inside or swap out the hard drive for any 2.5-inch SATA SSD. The machine comes with only one of its two memory slots filled, so you can pop in an extra 4GB, which costs around $33, for a total of 8GB. A 240GB or 250GB SSD goes for between $90 and $100. When there’s a sale, you can get both components for far less. So, for $480 or less, you can have this laptop with an SSD, 8GB of RAM and a 1080p display.
Battery Life: Great for the Size
If you don’t mind carrying the Aspire E 15 around, you’ll really appreciate its long battery life. The laptop lasted 8 hours and 16 minutes on the Laptop Battery Test, which involves continuous surfing over Wi-Fi. That time is an hour and 20 minutes longer than the category average (6:52) and around double the time of the Dell Inspiron 15 5000 (4:25) and HP Notebook 15 (3:36). The 14-inch VivoBook E403SA (9:02) lasted a bit longer.
Webcam: Too much noise
Even in a market in which most built-in laptop webcams take poor pictures, the Aspire’s 720p sensor stands out for all the wrong reasons. When I shot a selfie under the flourescent lights of my office, both my facial features and the background behind me were filled to the brim with extra visual noise. Fine details like the hairs in my beard and the lines on my skin were hard to make out.
The E 15 is certified for Skype for business, which means that its microphone, speakers and webcam are guaranteed to work with Microsoft’s enterprise-friendly conferencing software. However, given the image quality of the built-in lens, we recommend purchasing an external webcam if you plan to make video calls for work.
Heat: Pretty cool
The Aspire E 15 stayed cool and comfortable to the touch throughout our use. After I streamed 15 minutes of video, the touchpad measured 78 degrees Fahrenheit, the keyboard clocked in at 84 degrees and the bottom hit only 85.5 degrees. All of those temperatures are well below our 95-degree comfort threshold.
Configuration Options
Acer’s Aspire E 15 family comes in a wide variety of configurations.If you’re willing to spend a couple hundred dollars more, the $579 Aspire E5-575G-57D4 has the same screen and chassis as our review model, but features a Core i5-7200U CPU, 8GB of RAM and a 256GB SSD. The $629 E5-575G-53VG adds Nvidia 940MX graphics.
Software and Warranty
Acer preloads the Aspire E 15 with just a handful of utilities that aren’t harmful but that mostly duplicate built-in Windows 10 features. Acer Care Center checks the system health and looks for software updates. Acer Power Button sets what the power button does: turn off the computer, sleep, hibernate or disable the display, but all those options are also available in the Windows 10 control panel. Acer Quick Access allows you to turn on the Blue light-reduction mode or set up your computer as a hotspot, features that you can get as part of the OS. CyberLink’s PowerDVD lets you play movies on disc.
Like every other Windows 10 laptop we’ve tested, the machine comes bundled with Microsoft’s standard load of casual games and trialware, including, Sling TV, Candy Crush Soda, Royal Revolt II, March of Empires: War of Lords, a link to download Fallout Shelter and a link to download Asphalt 8.
Acer backs the E 15 with a standard one-year limited warranty. See how Acer did on our laptop brand ratings and tech support showdown.
The Bottom Line
The Acer Aspire E 15 E5-575-33BM offers a great combination of solid performance, good battery life and strong usability for the money. You’d be hard-pressed to find another 15-inch laptop with features and build quality this good selling for anywhere near $350.
If you’re looking for a lighter laptop with longer battery life in this price range, consider Asus’ 14-inch VivoBook E403SA, which costs $50 more and has much weaker performance, but weighs just 3.18 pounds and lasts over 9 hours on a charge. However, if you want the best budget 15-inch laptop available right now, look no further than the E 15 E5-575-33BM.

According to our colorimeter, the Acer E 15 can reproduce an impressive 159 percent of the sRGB color gamut, which is well above the 94 percent mainstream laptop average. That showing also trounces competitors in the E 15’s price range, such as the HP Notebook 15 (70 percent), Asus VivoBook E403SA (68 percent) and Dell Inspiron 15 5000 (72 percent).
Unfortunately, the numbers here don’t tell the full story, as the viewing angles were quite narrow. Dark images began inverting at just 45 degrees to the left or right.
Don’t try using this laptop in direct sunlight. The Aspire E 15 E5-575-33BM registered just 215 nits on our light meter, well below the 276-nit category average but actually better than showings by the Notebook 15 (174 nits) and VivoBook E403SA (201 nits). The Inspiron 15 5000 (213 nits) had a nearly identical score.
Audio: Decent
The Aspire E 15’s speakers offer output that’s quite accurate and loud enough to fill a medium-sized room. When I played Deep Purple’s “Smoke on the Water,” I could hear a clear separation of sound amid the drums, vocals and guitar. There was only a hint of tinniness in the high tones.
Performance: Ready for (light) multitasking
With its Core i3-7100U CPU, 4GB of RAM and 1TB 5,400-rpm hard drive, the Aspire E 15 E5-575-33BM offers just enough performance for light multitasking. With 12 tabs open in Chrome and a local 1080p video playing in another window, I experienced minimal lag when switching between the tabs. However, when one of the tabs was streaming a video (in addition to the local video) or downloading a large web page, things slowed down to the point that letters I typed in a Google doc didn’t appear until seconds after I hit the keys.
The Aspire E 15 scored a modest 5,408 on Geekbench 4, a synthetic benchmark that measures overall performance. That’s much less than the Core i5-7200U-powered Inspiron 15 5000’s score (6,742), but better than the showing by the HP Notebook 15-ba009dx (3,291) and its AMD A6-7310 CPU.
Acer’s laptop took 5 minutes and 14 seconds to complete the Laptop Spreadsheet Macro Test, in which we match 20,000 names with their addresses. That time is slower than the 4:01 category average and the Inspiron 15 5000’s time of 4:03, but more than twice as quick as the times from the Pentium N3700-powered Asus VivoBook E403SA (13:31) and the HP Notebook 15 (11:40).
The E 15’s 1TB hard drive copied 4.97GB of mixed-media files at a rate of 36.6 megabytes per second, which is significantly slower than the result for the Inspiron 15 5000 (83.4 MBps) and a bit lower than the HP Notebook 15-ba009dx’s showing (40 MBps), both of which have 5,400-rpm hard drives. The VivoBook E403SA and its eMMC memory did even worse (30.1 MBps).
You can watch full-HD movies on Acer’s laptop, but don’t think about playing anything more than casual games on it. The E 15’s Intel HD 620 GPU managed a mediocre 49,211 on 3DMark Ice Storm Unlimited, a synthetic graphics test. That mark is well below the Inspiron 15 5000’s score of 60,475 and the category average (86,474). However, the Notebook 15-ba009dx (33,649) and VivoBook E403SA (26,224) scored even lower.
Upgrading: Encouraged
Unlike many manufacturers, who don’t want you to touch your laptop’s innards, Acer actually cites the easy-to-remove upgrade panel on the bottom as a reason to buy this laptop. If you want to improve the performance of the E 15 E-575-33BM, you can upgrade its RAM and storage drive easily and inexpensively.
Once you take the panel off, you can put up to 32GB of DDR4 RAM inside or swap out the hard drive for any 2.5-inch SATA SSD. The machine comes with only one of its two memory slots filled, so you can pop in an extra 4GB, which costs around $33, for a total of 8GB. A 240GB or 250GB SSD goes for between $90 and $100. When there’s a sale, you can get both components for far less. So, for $480 or less, you can have this laptop with an SSD, 8GB of RAM and a 1080p display.
Battery Life: Great for the Size
If you don’t mind carrying the Aspire E 15 around, you’ll really appreciate its long battery life. The laptop lasted 8 hours and 16 minutes on the Laptop Battery Test, which involves continuous surfing over Wi-Fi. That time is an hour and 20 minutes longer than the category average (6:52) and around double the time of the Dell Inspiron 15 5000 (4:25) and HP Notebook 15 (3:36). The 14-inch VivoBook E403SA (9:02) lasted a bit longer.
Webcam: Too much noise
Even in a market in which most built-in laptop webcams take poor pictures, the Aspire’s 720p sensor stands out for all the wrong reasons. When I shot a selfie under the flourescent lights of my office, both my facial features and the background behind me were filled to the brim with extra visual noise. Fine details like the hairs in my beard and the lines on my skin were hard to make out.
The E 15 is certified for Skype for business, which means that its microphone, speakers and webcam are guaranteed to work with Microsoft’s enterprise-friendly conferencing software. However, given the image quality of the built-in lens, we recommend purchasing an external webcam if you plan to make video calls for work.
Heat: Pretty cool
The Aspire E 15 stayed cool and comfortable to the touch throughout our use. After I streamed 15 minutes of video, the touchpad measured 78 degrees Fahrenheit, the keyboard clocked in at 84 degrees and the bottom hit only 85.5 degrees. All of those temperatures are well below our 95-degree comfort threshold.
Configuration Options
Acer’s Aspire E 15 family comes in a wide variety of configurations.If you’re willing to spend a couple hundred dollars more, the $579 Aspire E5-575G-57D4 has the same screen and chassis as our review model, but features a Core i5-7200U CPU, 8GB of RAM and a 256GB SSD. The $629 E5-575G-53VG adds Nvidia 940MX graphics.
Software and Warranty
Acer preloads the Aspire E 15 with just a handful of utilities that aren’t harmful but that mostly duplicate built-in Windows 10 features. Acer Care Center checks the system health and looks for software updates. Acer Power Button sets what the power button does: turn off the computer, sleep, hibernate or disable the display, but all those options are also available in the Windows 10 control panel. Acer Quick Access allows you to turn on the Blue light-reduction mode or set up your computer as a hotspot, features that you can get as part of the OS. CyberLink’s PowerDVD lets you play movies on disc.
Like every other Windows 10 laptop we’ve tested, the machine comes bundled with Microsoft’s standard load of casual games and trialware, including, Sling TV, Candy Crush Soda, Royal Revolt II, March of Empires: War of Lords, a link to download Fallout Shelter and a link to download Asphalt 8.
Acer backs the E 15 with a standard one-year limited warranty. See how Acer did on our laptop brand ratings and tech support showdown.
The Bottom Line
The Acer Aspire E 15 E5-575-33BM offers a great combination of solid performance, good battery life and strong usability for the money. You’d be hard-pressed to find another 15-inch laptop with features and build quality this good selling for anywhere near $350.
If you’re looking for a lighter laptop with longer battery life in this price range, consider Asus’ 14-inch VivoBook E403SA, which costs $50 more and has much weaker performance, but weighs just 3.18 pounds and lasts over 9 hours on a charge. However, if you want the best budget 15-inch laptop available right now, look no further than the E 15 E5-575-33BM.
