It is good quality but only holds in a tilt up to 90°. This practically means that depending on the weight of the mobile or tablet or the viewing angle, you may have a problem with it standing. Also, it is not adjustable in height. Therefore, it is not very practical.

Very stable. It lifts the tablet (iPad 10.5) to eye level. But it also fits a mobile phone. The only trick is that I put something very small (a piece of paper, etc.) behind it (in the "joint") to lift it up a little more upright.

It is the best stand that someone could buy. I have had it for about 6 months and it proves to be an amazing purchase. I use it on my iPad 10.5 and it comes in the perfect position on my desk in relation to my eyes, it is stable and easy to use with my hand, although I mainly use it with a mouse and keyboard, and finally, it has a very good price.
