I agree with what is being said. Sorry, but I just joined this group today.
I have been using the Medtronic sensor, now the MMT-7020A, and the accuracy really stinks. I rarely have a sensor where the accuracy is +_20%. Whenever I call Medtronic they respond as if I only started using the sensor last week. After 3 years of this frustration of lousy sensor accuracy , I called the FDA today and filed an official complaint. Probably won’t do much good, only time will tell.
I am thinking of using the DEXCOM sensor instead of Medtronic. Is there anyone who has used both sensors that can tell me if the DEXCOM is any more accurate than Medtronic?
