I’m about to move from G5 to G6, and because Dexcom made a wrong assumption last year, now have five extra sensors. I find that reassuring, because of the number of times Dexcom had to replace G5 sensors, and the number of times within that that they replaced them very slowly.
The G6 labels say they expire this July. I don’t think they’re “smart,” unlike the transmitter. My operating assumption is that if I hit blood on insertion and have to call for a replacement, I simply do not know the lot number or any other identifying information. I think they ALWAYS ask for my transmitter serial number, even though the transmitter almost never is the problem.
Also, if anyone is in need, when I change to G6 I will have a number of G5 sensors and an untouched transmitter that should find a new home. Machiya at rdrop dot com.
