I too use a RIP-OFF pager case. The plastic clip on my fire pager broke and found the nylon RIP-OFF pager case as alternative to having it fixed. However, I have "lost" this pager several times since then, including one time when it flew to the trauma center with a patient I had been treating. It slipped off onto the backboard straps unnoticed. I find I must compress the metal clip once or twice a week to ensure it stays in place. Pete
