Our OmniPod start has been very, very rough. Like, I want to take every single one of them out in the driveway and run them over with my car, rough. We had to fight to have an entire box replaced because every one in that box, without fail, fell right off his body within 24 hours. We still have to do things I don't think anyone should have to do to get them to stay on (he's very, very active and we accept that, but it's just one more step in the many things I have to do every day to make sure it stays on him). Now, having said that, I can't imagine going back to MDI full time. He went on it last Saturday evening so that DH and I could go out. I didn't think it was fair to the babysitter to have to check him every 2-3 hours like we do. That's the other thing. On MDI, we were checking him once when DH got up for work at 2:30 to 3am. With the pump, and before the CGM, we were up every 2 hours. That might be with any pump, but our only experience is with OmniPod. Out of 30 pods, including those that fell off within 24 hours, we only had one bolus failure (with .5 units left) and they replaced that, no questions asked. We had one where something went wrong with the insertion and it really hurt him. Were shots easier on US (the parents)? Sure. Were they easier on him? No way! The other thing you have to remember too....if a pod fails, or falls off, or whaterver, and it doesn't make it the 2 to 3 days, you lose all the insulin in it. That's been a little frustrating and after the first week, we never put more than 125 units it it because we were losing so much that couldn't be replaced. As far as the "click" when the cannula goes in...my son said the worst part is the noise it makes because he doesn't feel it when it actually goes in. good luck in whatever you decide!
