I don't know about you, but this is not what I wanted to see when my daughter pulled her pump out to bolus for dinner tonight - The pigtail tubing was completely severed. It must have just happened because it didn't seem to have any effect on her BG (and she was playing outside before dinner, so that probably helped). Called it in, and they are sending a new box of cartridges. I wonder if it was flawed or my daughter just got it caught on one too many cabinet knobs or something. . .
