At first I expected that the sticker would cause me problems because the place I chose was not a smooth surface, but that was not a problem. It stuck so well I might have trouble removing it. Second, be careful as a ridge rises above the round part of the device. Make sure you don't block the camera with it. Regarding its operation; the rotation function is great but spins too freely. It needs to be tighter so it stays in place a little better. Also, the bottom of the ring, the "flat part" that forms the "leg" when used as a stand, can be slightly wider, making it slightly more stable when placed on a table or other surface. In general I like it. A few small improvements make it great. hope it lasts
