Asus ZenBook S UX391U (Core i7, FHD) Laptop Review


13.3-inch lightweight. The ZenBook S (UX391) is a particularly light 13.3-inch laptop from Asus. It tips the scale at just 1 kg, but the manufacturer says the performance is not affected. We review the rival for the XPS 13.

high-quality metal case; light and slim ; matte FHD screen ; quiet operation, optional Quiet Mode ; 2x Thunderbolt 3 ; docking station & sleeve included ; decent input devices

mediocre performance utilization ; fan quickly spins up under load ; battery runtime could be longer ; no SD reader ; occasional electronic noises

How much performance does a mobile device need? Slim devices often have issues to utilize the performance potential of the current mobile quad-core processors. However, everyday tasks usually do not need that level of performance. We like the approach...

Asus ZenBook S UX391 review


Elegance, speed and utility. Is this the ultrabook you should buy?

Ultra portable ; Amazing screen ; Feels strong and sturdy ; The keyboard is awesome ; The ErgoLift hinge is helpful

Battery could have been better ; Dongle life

This premium looking ultra-portable machine raises the bar for its competition
