[Archaic punctuation reference alert] For clarity, if I had meant to be insulting I suppose I could have used a ‘sarcastrophe’, the written equivalent of doing those little wiggly-fingers-in-the-air gestures which consists of a caret around the text. That would have been ^great^.
In other news @Tim, do people usually say ‘battery cap’ on these kind of threads? Might be worth phoning Medtronic for a replacement?
