I have an ATT 8525 phone with a belt swivel holder. The plastic belt clip portion of the phone holder lasted a week. I found these replacement swivels on Amazon and thought I would need a lot of replacements at my rate of use and breakage, so I ordered a few. I have had the same one now for almost 2 months and no sign of wear or tear on it. I will keep the others just in case, but these universal clips seem to be the answer.
