I bought me this slip mat here recently. Hab first cleaned the place where I attached it with water and a touch of glass cleaner and only then it stuck the mat. So it keeps 1A on the dashboard and also does not dissolve when I solve an object thereof. Put my phone there and it is now among the phones not degrees so the lightweight) cash and mobile phone also hold stronger braking out. Must this also say that I have it mounted on a relatively straight face. I think very wrong or vertical surfaces would pad not perfect endure, but that is just a hypothesis, in my hälts super :)
