Today I received it and unfortunately, with disappointment, I found out that it does not work with the screen of my tablet, which is a Lenovo M10! Otherwise, it works perfectly with the screens of two family phones, one Xiaomi and one Samsung!! The thing is that I wanted it for use on the tablet, so I messed up!!! As for the construction and material, it seems fine to me!!! I just can't express an opinion on its functionality yet, as I haven't had the chance to try it!!!
