Great service from NewEgg on an awesome little laptop 7/10/2020 10:09:25 AM

Pros: Really nice laptop. Very lightweight and powerful; It feels lighter than a Dell XPS. The 4K screen is gorgeous.

Cons: The speakers are weak and Asus ships it with Net Framework 3.5 turned off. I have some old 32 bit apps that need Framework 3.5 and I had to turn off McAfee and the encryption utility before I could turn Framework 3.5 back on.

The fan kicks on once in awhile and it's noisy.

Overall Review: 7/10/20. I have to revise this review way down after just 3 months. The machine is dead. It started with the speakers failing and having to disable and enable the drivers to get them working again. Then, in the last week it started throwing Thunderbolt errors every time it boots up, then the WiFI failed and reinstalling the drivers for that only worked the first 6 times I had to do it. Now it doesn't boot up at all. I've installed every Windows 10 and Asus update available up to this point, and nothing helps. I loved it while it worked, but I'll never buy another Asus machine if they only last 3 months.

Dear Nancy N.,

I'm sorry to hear that your laptop is no longer booting. All ASUS products undergo intensive quality control, testing and inspections. What you've experienced was not intentional or representative of our brand. If you purchased the unit brand new, then you are still well within warranty. Please reach out to me at and include case #N200750367 in your email for reference. I'd be happy to get a warranty repair started for you.

Thank you for choosing ASUS!

Elegant and innovative but the battery... 6/3/2020 12:31:27 PM

Overall Review: I've been using this laptop for a while.
There's no doubt on the innovative and the elegant look, the lightness and the portability of this little machine.
But the battery is really bad...
I've disabled the bluetooth, touchscreen input, back-lit keyboard and the brightness on the lowest settings,
but the battery keeps drowning and only this but paramount drawback makes me rate this product 4 out of 5 eggs (stars).

Sweet unit 4/25/2020 6:31:29 PM

Pros: Build Quality is excellent, rigid chassis, incredible screen and fast hardware. Although it is a fingerprint magnet (sigh). Keypad feels nice, just the right amount of tactile feedback for me. Thunderbolt 3!!! I don't use this for intensive apps so heat seems fine. Very portable and light PC. I would recommend

Cons: Some times when coming out of sleep mode wifi wont connect without reboot. Software issue I suppose.
Glossy screen is troublesome in the sunlight but the UHD is clean.

Overall Review: Very happy so far we'll see. Great for a light POWERFUL ultra book.

Not for me 10/16/2019 10:51:26 AM

Pros: Very sleek unit, powerful with an amazing screen, while it worked!

Cons: The unit has Thunderbolt and USB-C connectivity. We needed to add two 1080p external monitors of the Thunderbolt via adapter. Everything worked for 8 business days then suddenly we started to have problems. First we lost Thunderbolt functionality (monitors) and then the wireless and Bluetooth stopped working as well (Internet, KB and mouse). So no connectivity what so ever. We worked with Asus tech support for over a dozen hours installing drivers and factory resetting the unit. Asus tech rapidly defaulted to return for repair. Since this created problems for us we persisted in trying to fix the issue to no avail. We finally returned the unit for store credit.

Overall Review: While it worked, it was a fine laptop exceeding expectations, to bad it did not work for very long!
