Andreas Osthoff | May 2023
"The Asus Zenbook S 13 is the slimmest OLED ultrabook worldwide struggles with annoying fans. The new Zenbook S 13 leaves us with mixed feelings, particularly since last year's model was so good. Asus has completely reworked the device, making the laptop noticeably slimmer. The result also looks good and the case makes a great impression, particularly also in terms of the stability. The new plasma ceramic surface feels great, and there are no problems with fingerprints. In addition, it now includes some of the known connections such as an HDMI port and a regular USB-A connection, which is a good achievement in such a slim device."

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
