The hinges are quite stiff so if you need to adjust it quickly it's a bit finicky. It requires a solid amount of strength to adjust so if you want do it with your tablet on there you just have to be more careful on the level of control.
It would better if it was heavier to allow more angles and heights, I currently have it on an iPad Pro 12.9" and certain adjustments will make it quite unstable.
Some of the rubber padding isn't fully stuck on, particularly on the bottom area. Also it would of been good if the rubber padding on the back where the tablet rests is higher so my iPad doesn't hit the metal hinges.
It works fine but if you're looking for a more premium product this doesn't quite fit.
