A:Answer I would guess that the wall would have to be very smooth and clean. It’s actually made to stick to glass (car windows) or smooth metal surfaces (outside car door, roof, hood). If the wall is textured at all, it won’t stick. As far as weight limit - it’s made for small cameras like the GoPro. It handles my iPhone 12 Pro with an aluminum phone holder just fine. I attach it to the windshield and side windows for POV footage. The footage can get shaky. I’m not sure if it’s the roads here, older car, length of the arm, weight of the phone & holder, or some combination.
