LOVE!!! PROS: It adheres fast, and is long lasting. The swivel is so incredibly smooth, unlike others that feel as if it will break off. Very sturdy, and works in all angles. Sleek! It does not catch on clothing while putting it in a pocket, and isn't super bulky.CONS: I have not figured out how to remove from a case, so I just ordered a new one. This isn't really a "CON", but is the only thing I could think to improve. I would highly recommend this for a case (MAYBE EVEN FOR OTHER DEVICES, TOO!!)I originally ordered this ring for my waterproof A52 phone case last October, but the case did not work for everyday use (perfect for canoeing or such). So, I found a new case and ordered another ring. STILL LOVE IT!! Love it so much that I ordered a third one for my son's new phone case after raving about it. I would recommend and would buy again in the future.
