So I have a question for everyone using the Dexcom Seven Plus. We have been using it on both of my girls for about a month now and from day 1, Elly's has been nothing but trouble. The 1st sensor I placed on her the 1st week had several sensor 1 errors and several ???. The 2nd weeks that sensor seemed to do OK but then the 3rd week, I had 3 sensors fail during the 2 hour start-up. After that happened, Dexcom sent us a new transmitter and, fingers crosses, so far so good. Now, up to that point, Anne's had been acting like a model citizen. Then today I went to do a sensor change on her and I had 2 sensors fail! I couldn't believe it. Dexcom tech support couldn't figure out what was up. I sent them the information from the receiver and they also said that she has several 10ish minute gaps in data that isn't normal as well so they are sending a new transmitter and receiver for her (of course we won't get it until monday due to today being Friday). I just don't get why we have had so many problems with BOTH of the girls in the 1 month that we have had them on Dex. I am really hoping that we just got a bad batch and Anne's will start working like it should but I am just so frustrated. So I guess my question is if anyone else has had problems like this with Dex? I really don't want to switch to MM but will if this continues.
