I had mixed results with the MM CGM. Some days it worked well; others it did not. I did keep it on for 5 or 6 days at a time, but I also found that particularly if the adhesive got wet for more than 10 min (say, during swimming lessons) it was a goner.
This is definitely a YMMV issue. I've read over the responses from a lot of people, and some of them love it and some hate it; some get great accuracy and some get lousy accuracy. For me, it didn't work well enough in the low range for me to feel safe. So I got a Dex instead. I've only been low one time since I got it, but it DID catch it. That means a lot, since I'm relatively hypo-unaware. If the CGM doesn't alert, and I don't feel them until I'm in the 50's, that doesn't give me much wiggle room. But for those people for whom the MM works well, it's great! :-)
I may have answered this 2 years ago, but I hate it. The accuracy stinks. Totally.
agree with Spock. I was always testing with my meter to see if it was correct and it usually was not. Gave up after 6 months, was not a fan. I wanted it to be accurate and not painful.
My niece tried Minimed cgms because she has a Medtronic pump. The insertion always required EMLA and even then she claimed she was sore when EMLA wore off. She now has Dexcom which is very comfortable as far as needle size and EMLA not needed. The Gen 4 Dex is more accurate than Minimed's cgms and that has been proven in studies. So I would recommend Dexcom. PS there is a noninvasive cgms being released in Europe. Can't wait for it to be available here; I'm sure we will have a five year wait for that one.
I've said before (probably to the same people? LOL) that the Medtronics sensor works very well for me. Usually very close to the meter and, if off, is generally lagging behind by a pretty short time. The only time I've seen a Dexcom in action, my friends said 155 and she was eating and I was like "yikes!" and he said "my meter was 55" and was I like "oh, I didn't realize they did that..." since everyone is always so rah rah about them. I have a day here and there where it will run off, usually when I am messing around when I'm calibrating and stuff but I don't do that that often any my results with it are decent.
My doc was pretty offered me a Dexcom, or at least offered one the last time I was there. I'd sort of like to try one at the same time to see what it could do and if the claimed better accuracy is worth another dingus to lug around. I sort of doubt it. The display is obviously cooler though...
