A CDE that works for Medtronics told me that if you charge them offen and not let them completely discharge they will last longer I have had mine since nov. last year and been waring it 24/7 and still going. This is my first. I would personally shy away from a used one if at all possible.

This is great information. Thanks so much for replying. We weren't able to find this information on Medtronic's website. I think it's an important fact that should be posted. How have you liked the CGM? Has it worked well for you?

My CDE/CGMS trainer said they are guarnateed for 9 months (to the origianl purchaser), but that most people who do not let them ever totally die, are getting a year, maybe a bit more

I am curious to know if my insurance will pay for another transmitter after my current one dies in 8 months, they paid for the first one and I am sure Medtronic had to tell them life expectancy of the transmitter. Never a dull moment!!

Who is your insurance company? We're still trying to get ours to pay for the supplies.

I was never told this! I got the CGMS last September so does that mean I can expect my transmitter to die soon? I stopped using it the first time b/c I was getting inaccurate readings. I decided to give it another try a few weeks ago but had to order new sensors since the ones I had left had expired & they wouldn't take them back. I used it for a week but since have found out that my insurance may not be covering the sensors since they are "disposable" and not "durable" so I stopped using it for now. Now my transmitter might die too? *sigh*

I think the reason the transmitter goes bad after a year or so is due to the rechargeable battery failing. It is pretty small and sealed in the case pretty tight. If you have not been using your CGMS for a good while then I am sure it will last for many months. As far as accuracy you really need to give it a solid month of use. I find it to be very accurate overall maybe not at an exact moment like a meter but you really need to look at the trends and data on Carelink.

hope this helps

My husband decided to take his chances and buy the used CGM just to try it out. He's only been wearing it a couple of days, but so far it's been very helpful. He's been able to watch trends and be alerted when he's going low or high. The alarm woke him up the other night when he was at about 58. He was able to eat some glucose tablets and go back to sleep. He's noticed it's not exactly accurate and there's a delay in the reading, but overall we're happy to have it.

Melissa, I've used the Minimed pump for many years and now use the Minimed MiniLink CGM. I'm so disappointed with the minilink I wish I'd saved my money! I'm shopping around now for a new pump and CGM. I'll be so happy when I don't have to deal with Minimed people again! My MiniLink has lasted almost a year,, and I'm expecting the battery to go out any day now. At every sensor change, I put the transmitter on the charger for about 10 minutes and the battery has lasted this long now. If you want to buy a used one, I'll sell you mine!

Just curious as to what you didn't like about Medtronic? I have always had good experiences with them. I had 2 sensors go bad and I got them both replaced for free.
