I used it once and found it durable and easy to use. Assembly was easy. The part that flexes is strong and will withstand some pressure but will not break. The only thing that would make this ideal would be if the straight part of the brace could go up and down. To lower the tray, you need to bend the stand down. With my Surface Pro, the mount was secure. I think it's about as big as it needs to be, but it still holds it without tipping over.
