Younger son was using the MM CGM with Enlites because of unresolved rashes on the Dexcom. We also have the new Dexcom G4 with Share trying to see if we can keep the skin rashes at bay. While wearing the MM, the MM transmitter fell off the sensor and went into the pool. Stayed at the bottom for a while. It was a salt water pool if that matters. We have had it in rice and it doesn't work yet. I will have to pay out of pocket and get a new one. Even with using flonase and tapes underneath, he still gets a rash that takes weeks to totally go away from the Dex. So we go back and forth on which system he uses. Because insurance paid for the new Dex I understood that I will be paying out of pocket for this new transmitter. Just wish it would work again. It is just out of warranty , but those MM last a very long time for us.
