Typing is now more comfortable than ever with the full-size one-piece chiclet keyboard. An improved back-assembly provides 1.8mm of key travel and minimal key float, so you get a more solid typing feel.

Intuitive ASUS Smart Gesture Input

ASUS Smart Gesture technology utilizes an intelligent combination of hardware and software optimization to give you precise input. Sophisticated smartphone touchscreen production methods result in a highly sensitive touch pad that allows you to pinch-zoom in and out, or scroll through images and webpages with ease.

Good Insides Bad Outsides 11/4/2016 3:01:24 PM

Pros: - Good (or even generous) Specs
- Stays at a decent temperature
- Number pad

Cons: - Everything else feels cheap
- Keyboard is awful and makes it hard to type fast
- Screen has a very poor viewing angle, black edges are apparent even when its angles straight at you
- Trackpad feels like it's made of an unusual material
- Clicking with the trackpad is janky

Overall Review: On paper, this laptop sounded great but it doesn't help to have good core components when everything external you have to interact with feels like garbage. It makes for a very bad experience.

Works good, but poor quality 8/8/2016 12:09:56 PM

Pros: Fast computer, can run most things you would need.

Cons: -Felt like it was made cheaply, not a computer to haul around with you, acquired a lot of dents during its use when I carried it to classes.
-The keyboard is made out of a thin plastic that seems to flex as you're typing.
-The screen is low quality, terrible viewing angles, and didn't satisfy me, as I was looking at the screen for long periods of time. Once again seems as if it was made out of cheap materials.

Overall Review: Overall, it works great, but it has a low build quality, would not recommend purchase.

Worked fine for about a year 8/1/2016 6:55:49 AM

Pros: Laptop worked fine for the first year - didn't have any problems and it performed as advertised.

Cons: After about a year the sound started to cut out; if I pressed down on the upper surface on the right side, it sometimes came back. Otherwise, it could take several reboots before it came back. Definitely a hardware issue.
After this problem had been going in for around a month, the OS decided to crash as well.

Overall Review: I would probably not recommend this laptop based on its 1-year lifespan. if someone were determined to buy it anyway, I would let them know a couple things:
1) It does not come with an OS disk, so make sure you make a recovery disk first thing - don't put it off, because you'll probably keep doing it until it's too late. If you have to get repairs under an extended warranty offered through NewEgg, be aware that it is NOT with the manufacturer and they DO NOT reinstall the OS. You are responsible for obtaining the means for reinstalling the OS when it returns from being repaired.
2) The extended warranty company operates entirely separately from NewEgg or Asus. Once the initial 1-year manufacturer's warranty is up, you're pretty much on your own dealing with the extended warranty company. Good luck with that. To be honest, I would have avoided the extended warranty completely if I had known what it would be like trying to get a repair set up. It took a little under a month to get things arranged; the warranty company hands off the actual repair to ANOTHER company, and there can be a disconnect between the two that causes unnecessary and frustrating delays.

Great laptop for overall use! 3/9/2016 10:33:11 AM

Pros: *Intel Processor - Fast and Cool

*Dedicated Card - Nvidia 940M, decent card and plays what I need it to, without too much fuss.

*At the time of the buy Price

*Laptop stays cool for the majority of the time. I have rare instances where it will heat up and you feel it however I have it on a Cooler Master Cooling Pad with USB ports and seems to give me no issues.

Cons: *Speakers - Muddy and no real clarity, not really a con for me as I usually have a headset while doing what I need to.

*Screen - As with more reviewers this is the only really big thing for me, the screen depending on the angle which you have the monitor makes an enormous difference with the viewing. This is the one of two things I wish I could of changed on this buy.

*lack of 2nd dimm slot and inability to support 16GB, max 8GB - Not a big deal currently however longevity will be shorter due to inability to upgrade to a 16GB due to no second dimm.

*Keyboard - A bit flimsy but not a deal breaker for me, I use a gaming keyboard in place of this but for some it is a bit scary about the bend and flex on this keyboard however never had issues with it typing nor any issuses while using the computer due to the flexing.

Overall Review: At the time I purchased this, I was able to get this for roughly $578.00. It was a tough choice between a AMD variant however the intel core and graphics card choice won me over with heat and energy efficiency. If it was between these two again and the price point, I would still choose this laptop.

Disappointing Quality 1/23/2016 2:07:20 PM

Pros: -None, really

Cons: - Very poor build quality. I feel like every move I make is going to break it.
- Keyboard (while subjective) is very poorly spaced and you have to hit the tiny spacebar very hard to get it to work.
- This thing is SLOW. I know that everyone's computer is configured differently, but I used an SSD instead and, with the base system configuration and an SSD, this thing should be a heck of a lot faster.
-Screen is a good size, but is not very bright and has TERRIBLE viewing angles.

Overall Review: After using this computer for a few months, I know it is not really possible to have this thing returned for a full refund. I just want everyone to know that buying this laptop is NOT a good option. And while I mentioned earlier and am aware of the fact that performance is subjective and based on a configuration, I have pretty good experience with how to optimize a computer. This computer is WAY too much money for what you actually get, in terms of performance. It looks good on paper, but is not worth it.

Decent laptop for the price 11/14/2015 9:21:50 AM

Pros: 1080p screen, DVD drive, dedicated GPU, numpad for the keyboad, keeps cool under load

Cons: Build quality a bit cheap, not an IPS display, fan is a tad loud when under load

Overall Review: So far it's been doing very good. It's especially good getting it on sale or on clearance. Works fairly fast and has a decent GPU. Had to fiddle around with Nvidia Optimus for some things but not bad. Keep in mind, GPU/CPU performance will drop like a brick if it's not running off AC. I'm still working on seeing if it's possible to run at full power with the battery.
