What reviewers say

Reviewers praise the light, sturdy body, excellent keyboard and colourful displays. Laptop Mag finds strong endurance from its FHD model but weak speakers. Notebookcheck likes the brighter HDR panel yet warns about reflections, heat and fan noise under load. Both appreciate having USB-A alongside Thunderbolt; maintenance and soldered memory limit upgrades.
