This ring protects the camera from direct contact with the support surface. The ring fits snugly and keeps me quite some time without any problems although I always slide the phone in your pocket and always ensure that the ring waiting for this maneuver times goes off.
Unfortunately I can not give the full number of points. Since the price with the shipping cost is more than exaggerated.
Did the same ring, with hindsight, found by chance in a China Shop for pennies does not include shipping costs.
