I am a very clumsy person, so it's important for me to have good protection for my phone. I have a textured phone case so I was worried that this ring would not stick to the surface. When I applied the ring to the case and used the clear sticker provided between the ring and the case, the ring did not stay attached at all. So I tried attaching the ring directly to the case (I did not even change the 3M sticker) and it worked perfectly. I haven't even had the ring for 24 hours yet, so I can't provide any information about the long term, but so far I am happy.
