I wanted to use it as a universal bracket for all sorts of phones. I was sorry to have to always buy 5 new, device-specific holders every two years. The Pad sticks like the devil. I had just afraid it would tear out my phone the back. It is necessary to a phone with glass back (that is, all modern smartphones) to remove considerable effort. Therefore, I do not use it for my phone. Certainly one could cover the surface partially or deliberately contaminate. But that's my opinion does not make sense. The bracket keeps its promises. The point deduction is available for the limited manageability. It adheres always "full Lotte" and thus much too strong. The pads to be placed on the dashboard are not quite as joyful way, a phone must also not held vertically.
