I bought this to replace a broken, non-rotating clip for a Cellet case I really like for my Motorola Razr.  The old one broke because it kept getting hung on chairs, seatbelts, etc.  I can rotate this one out of the way and can get to the phone whenever I need to.  The rotating clip should come standard on all cases, even if they have to supply both kinds.  How much can it cost them, 20 cents?
