Once attached to your device, these are quite stable and Strong. Can be taken off and reactivated with water, and reused. 360 Degree Free Rotation and 180 Degree Adjustable Angle. For All Digital Products up to 8lbs. I personally never cared to use one of these even though I had many in inventory, but I put one on for picture purposes and now I love it. Even when just holding your phone in your hand this gives you more security against dropping it. Wish I had put it on much earlier.
