Same exact thing happened to me. I kept thinking it was me. It wasn't . Finally, after going through hell(driving with my kids while my numbers went up to 300 while on a summer vacation,) I stopped the car, changed the pod again. Didn't work. Took an insulin shot which got me home. Literally. Called Medtronic that night. Got out my old Minimed, switched back over and never looked back. Yes, I hate the tether, but I will take the reliability any day, over the pod quandry of, will this one work?
