What reviewers say

Reviewers find it good value, with a thin and light build, quick everyday performance and very long battery life. Tom's Guide and XDA found the speakers crackly or tinny, and Tom's Guide and Gizmodo the webcam grainy; Gizmodo judged the IPS screen's viewing angles poor, recommending the OLED option, and warns that some Windows apps and games still don't run on Arm.
