Query: Very Brittle Plastic

The belt clip holster holds the phone nicely. There weren't any issues with the phone falling out. Unfortunately, the plastic the clip is made from is quite brittle. At first a corner snapped off, eventually the post that holds the belt clip at the rear broke off while getting out of the car. The clip survived about 3 weeks, whereas the original clip I got with the phone lasted 3 years (with a lot of abuse).
