This is at least my fourth Ping pump, counting the replacements for warranty reasons. It is the first to suffer a crack like this. I was aware of the caution to not over-tighten and thought I complied.
The insulin pump cartridge cap is just the opposite. If I don't get that one torqued down good and tight, I get "pump not primed alarms." Those alarms are a nuisance in that they require you to disconnect from the pump site.
Yes, I hope Animas corrected this with the Vibe but I sure wouldn't bet on it.
