I am not sure why I wasn’t happy with my second sensor, but I will say that every time I shut it down and restarted it, it became more accurate. I got a lot of calibration errors with it and I don’t know if it was the sensor, the situation (dog agility trial), or the meter. It finally stopped working on day 8. Yes, I stopped getting data from it. I tried several restarts, but couldn’t get it to budge.
I had the same problem with my third sensor. Come to find out, I did not insert it correctly. Dexcom gave me a credit for it, which I’ll be able to receive with my next order. They are also sending me a return kit for it.
Needless to say, I am definitely going to call tech support and have them walk me through inserting the next few. I skipped a step and maybe I’ll remember next time, but a) tech support is very nice and patient, and b) it doesn’t cost me anything to use their resources.
The fourth sensor, which I put in last night is working as well, if not better than the first sensor. That’s good because I’m driving to Pittsburgh tomorrow.
