Very sturdy and well thought laptop stand (even for a 25 key synth or controllers)! It's built like a tank, very very stable. A bit bulky, so consider that if you need something more compact.
Leg tubes are massive, consider that if you want to mount any holders onto it because most of brackets fit 35mm max. Locking mechanism for keeping the laptop in place are great with a lot of variability. The tray easily fits Macbook Air and an additional box like a small audio interface box. Overall a great purchase. I really like Gravity stands.
