So, I'm scheduled to start on the OmniPod this Thursday. My sister went on it a month ago and initially she loved it--then the problems started. She's had to return her PDM once because it failed and she's had three Pods fail. We're both wondering if she's a "one-off" (maybe the pods were from a bad batch or something) or if other people have also had these problems? If these are common problems with it, I'd really like to back out while I have the chance! Please, tell me your experience, good or bad!
