Yes, I should have mentioned it. We had a sensor pile. For a while they had us send them back (or was that just the OmniPods?) and eventually they started just shipping replacements whenever we bothered calling.

I had a particularly bad experience with the G4 CGM. I know that some people do actually really like the device. I don't know if it's that my kids are stick-thin and consequently don't have many good insertion points, so the sensor would more likely than not be in muscle tissue, or any number of other possible reasons... But I spent much more time cursing Dexcom's name and holding back the desire to throw the damn thing across the room than actually reading useful data.
