Really good quality, this was the only tray that met our needs for a large tray with free space at the bottom. But it's sinking. I want you to block him, but the weight of his tablet and the angle he wanted (looking at him more directly from the shelf, vers. on the table, looking up) makes it sink down very slowly. The husband ended up putting a small stuffed animal underneath for support, which defeated the open space underneath that he wanted... But it really helped when he was afraid to look at his tablet during his scale meetings. Certainly worth the money for the quality... but if you have a large or heavy tablet, keep children's toys handy.
