But let me tell you, the flygrip is a bear to remove if you ever have too. I will never again in life attach one directly to my phone. Firstly, you need something like a knife to pry it off the phone, while holding your breath and praying you don't damage your phone with the knife.
Once I finally got that thing off my phone I attached it to the back of a hard shell sleeve instead. NOTHING should be this difficult to remove.
Also, and this is just based on my use....I don't hold the phone any better with it than without.
