This has happened to me once before a few months ago. I didn’t call Dexcom about it, but if it happens again, I probably will.

@petesteve If I didn’t have such good results with the G7 over the G6 I would think that those 73.9% who made it 15 days would be the same people who could restart the G6 for 20 to 30 more days. The 25.1% failures would of people like me where the G6 failed regularly at 7 to 8 days.

I had six G7 sensors fail in April, and had to use finger sticks when on vacation on the other side of the continent. Colour me unhappy!  
I was in British Columbia and woke up in a lake of sweat.

All I could ever get from Dexcom is “ we will send a replacement.”
