Florian Glaser | August 2022
"Users who travel frequently and are looking for a portable laptop are in the right place with the Asus ZenBook 14. The sleek case is extremely light (1.2 kg) and surprisingly thin (1.5 cm). Outdoor use is also enjoyable thanks to the bright Full HD display, which is something that can rarely be said about laptops with TN or IPS panels. The excellent battery life complements this as well. Longer trips are no problem with the ZenBook 14. Another plus point is the high-performance Ryzen 7 5700U, which often leaves the Intel competition in the dust thanks to its large number of cores."

PCMag

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."
