Hey Bob. 25 days is great!! I've been using cgm for almost 2 years.I have mine on my upper arms, and the longest I've gone is 21 days. Never had an infection. My last batch of sensors have all quit at 12 days. I hope MM hasn't figured out a kill switch!

Most of my sensors quit in the 9 to 12 day period. However, occasionally I get to go longer. Of course sometimes they lose their effectiveness in 6 or seven days.

I have been on the medtronic CGM for over a yr and the most I have gotten out of one sensor is 19 days I use the top of my thighs as well.

20 days is my best. I was trying my current one, but today(day)11) it just went south on me.
Good luck... and I think the fda is so full of it..on so many levels it's not funny.

You guys are remarkable! The longest I ever went (on the MM) was 7 days, and I really should have changed on the 6th day. For me, the clue is that it just flatlines, I mean really flat, no humps or valleys, when I KNOW my BG is not that steady. Are there other things that you use to figure out when the sensor has died?

Just carefully remove the transmitter after 7 days and recharge it for 7 hours. Not all will continue working accurately but many of them will. I'm not sure what the reason is but some of the sensors last longer than others.

The sensor will recharge in less than an hour. As soon as the light stops flashing, it is done.

After some problems, I made a phone call to Medtronic and they advised me to charge the transmitter for 7 hrs instead of 20 minutes. Ever since the transmitter has run strong for 7 days.

Hi Folks, The best that I have done is 7 days. I use a pretty sticky tape to keep the thing on my thigh and there is no way to take it off without buggering up the sensor. It has created a system that works for me, I change it Sunday morning because that is when I start getting the "sensor error" messages. Once a week is fine with me. Plug it in Sunday morning,mid afternoon it is ready for the first "test,bedtime test is good for a good nights sleep and I don't worry about it till the following Sunday.
I also change my pump junk every 4 days. Please don't tell the FDA on me. YMMV. Good Luck

I'm on day 27 and the sensor is still doing great!

I changed my sensor this morning after 30 days. It was actually still working, however, it was losing its accuracy and I didn't want the site to get infected.
