Query: Flawed design

The holster came in very handy until it broke. The design is flawed. The area near the top, just above the belt clip handle, has a cut out for the speaker. The cut out leaves very little material for strength of the entire top area that actually locks the phone into the holster. I bumped the phone against my desk chair and I heard a snap but the phone didn't drop out because of the cupped area on the bottom holding it in. So I didn't think much of it until I tried to remove the phone and it just slipped right out. Then I saw that the locking area broke off at the weak spot. This was with a very small bump against an office chair. The very brittle plastic probably didn't help. Thanx but I don't wanna risk putting my new Blackberry into a holster this weak.
