Review: Amazing laptop - Absolute beast of a laptop. It is the best laptop I ever owned. Build quality is amazing and the case is full aluminium. The CNC logo on the lid adds a nice touch. It looks great closed or open. The OLED screen is second to none, and it is great to type on. The touchpad is also quite nice. The battery life is great for such a powerful CPU. It plays many games that you would not expect an iGPU to be able to play. The ratio of the display is the old fashioned 16:9 which is very good for media consumption and gaming, as it does not have to display black bars like on 16:10 or 3:2 displays. The CPU and GPU generate a bit of heat but the cooling system is very adequate. 10/10 for the price
Review: Zenbook s16 Oled. Performance with style and Sophistication! - Stunning laptop combined with superb performance and graphics! Delivered in equally exquisite packaging. Real style and sophistication! The only negative for me has nothing to do with the laptop itself but concerned Windows update failures souring an otherwise great experience to date. Obviously that affects any laptop. 10 out of 10 for the laptop!

### ⭐ Good idea. VERY VERY VERY poor execution. Lots of DEFECTS!
*by T***V on 22 January 2026*

The Lumina OLED screen and AMD 370 are amazing. The style is nice. However, the laptop is so thin, you can feel they sacrificed very important engineering just to make it a couple of millimeters thinner. It's very loud, as the laptop has no room inside for proper cooling. After a bit of use, the touchpad burnt out. While I was troubleshooting, the laptop started making ticking sounds and I decided to give up and return to Amazon. As an electronics engineer myself, I have no faith in the system as composed by Asus and will not be buying a Zenbook ever again. It's very unprofessionally designed. If you do get one: Make sure it's not "Warehouse"/"Outlet" so that you have FULL MANUFACTURER warranty. Extend the warranty if you can - you will almost certainly need it.
