    • Lightweight (1.1kg) and slim, yet powerful (Core i7, 8GB RAM, 256 GB SSD)
Style: Core i7-8550 | 8GB | 256GB SSD
Lightweight and slim, yet fast enough for office work and entertainment. I'm not much of a gamer so I don't need a gaming computer, that usually requires a lift to carry it around. You can barely hear the noise of the fan and if you don't have it in maximum performance mode, the batter lasts 8 - 10 hours, with brightness at 10% (just enough to distinguish anything on the screen). It feels sturdy and the quality of the materials is beautiful. Some people may find the color a little odd, but I kind of like it, because it stands out. The screen is very good with vibrant colors and high definition. ... show more

    • Great laptop for what I do!
Style: Core i7-8550 | 8GB | 256GB SSD
This is a great light weight laptop with a head-turner design and color. The keyboard and touch-pad are nice and the design of the tilted keyboard is pretty useful. I do pretty much only coding on PhD level in engineering with this laptop and it has been pretty good so far (almost two months now). battery life is good and i also like the sleeve and the USB C converters that came with the laptop. ... show more

    • Progress of use declines

UPDATE MARCH 2021: Well, the laptop officially crashed. Really disappointed in this company. I always heard great things and this laptop stopped functioning. No, I did not damage it. Applications would randomly stop and crash, the computer itself would glitch and black out. I did nothing but use this laptop for school work. Trackpad stopped responding and fingerprint scanner would no longer read. Recycled it. UPDATE JANUARY 2020: My laptop has quite a bit of issues. My startup doesn't always allow me to log in and my keyboard doesn't respond when I want to brighten my screen or turn the back lit keyboard on. It's rather annoying. It won't work until I restart my computer or shut it off entirely. This laptop has grown into more issues. I can't sign in half the time, it glitches, my brightness doesn't work anymore (even with following Microsoft's advice of the device manager). I don't understand when I don't do anything. I don't eat or drink on my laptop, I have never dropped it or any other damage implicated. Disappointed in this progress of ownership. ORIGINAL: I sold all my Apple products and switched over to WINDOWS. I choose this laptop because friend recommended ASUS for easy simple use. It really is easy for someone who grew up on Apple. I love how lightweight it is and the purpose it has. I only bought this for nursing school, being able to research and write papers and study on Khan Academy. So far, the battery life is horrible, lasted longer on the MAC I had. I have been using the internet all day to study and it's almost dead. I understand it dying for heavy use with multiple applications open ... but not just for the internet. ... show more

    • Very fast laptop
Style: Core i7-8550 | 8GB | 256GB SSD
Very nice laptop. Light, very good quality build, runs long on one charge, no complains. Contrary to other reviewers, I don't see this laptop running hot, at least not during browsing, emailing, and this kind of light activities. The only complain I might have - the layout of the keyboard - especially power button, is awkward. PgDn,PgUp buttons are up in the 'function' keys row. Power button is in the upper-right corner - easily to me mistaken for 'backspace'. Also some of the keys (2 or 3 of them), when pressed, do not feel right. No click, and certain friction present. So far I was unable to find out how to downgrade this laptop to Win7. Win10 is just awful, but that's not the laptop fault. I wish Asus can release drivers for Win7... ... show more

    • Great option for a business laptop
Style: Core i7-8550 | 8GB | 256GB SSD
I am an IT Consultant so i get to see and test a lot of new computers. This is a beautiful, lightweight laptop! I have had it for about nine months now. It is a stunner! I get so many compliments about it when I take it to meetings or events. It is quick to start up and open applications. I love the solid metal build, it feels like a really high quality machine and is still so lightweight. The unboxing experience was also very nice! It would be a great laptop for a business professional that performs basic tasks like Microsoft Office and even QuickBooks. I didn't give the product 5 stars because I feel that it really lacks in performance for how much money I spent on it. After a while it started freezing more frequently and taking longer to launch programs at start up, it just doesn't seem like something that a $1,000 computer should do. You could spend less money and still get a machine that does the same things, it just doesn't feel like a Core i7. I did also notice the CPU buzzing sound that other people have mentioned in their reviews. The fans also seem to be pretty loud, even on the quiet mode. In hindsight I should have purchased a laptop with a designated graphics card because of the types of things I do (Gaming, Streaming, and LOTS of multitasking.) I haven't ever owned a gaming laptop before and had been able to play The Sims and other games just fine on my previous Zenbook. However this laptop will crash the game if it is set to anything higher than "Medium Low" quality. Sometimes it will even just crash the game on the low quality setting. A game like The Sims should not be that hard for a laptop with these specs. When live streaming games from a console it is close to impossible to have more than just that one program open. Now that I have more time for computer gaming and am doing more live streaming I am selling this laptop and purchasing an actual gaming machine. However, If i was still just organizing meetings and mostly using it for work purposes it would do just fine. It also seems to do alright with Adobe programs, again, only one at a time. Having Illustrator and Photoshop open simultaneously causes it to slow down significantly. I know it is intended to be a business laptop, but typically you can expect a lot more from a business laptop at this price. ... show more
