On September 30th, the old 2 and 3 CGM sensors were discontinued. Replaced by the 2 Plus and 3 Plus sensors.

If you or a loved one uses these sensors this will be informative. There is a problem with both. These sensors last 15 days now. And there is a new phone app. The app is called Libre, ot Libre by abbott.

I use c the 2 plus most Insurance plans prefer the Liber over Dexcom for cost considerations.

Enough background. The Libre sensors read your Blood Glucose Level (BGL) every minute and via blue tooth send it to your app on your phone. The sensor is worn on the back of either upper arm. Once on your arm it takes 1 hour to "warm up" before sending readings. Readings can be somewhat erratic for up to 48 hours. The sane was true for the older 2 & 3 models. But, now it continues for the sensor life of 15 days. For me my readings look 'normal' for 3 to 5 hours then I am doing nicely at 110 in 3 to 5 minutes I am at 52 , then 6 to 8 minutes later I am 154. 5 to 10 minutes later I back steady at 110. Nothing a diabetic wants to see or deal with. So I have confirmed the 110 reading with a finger stick.

Abbott, the company making the Libre is aware of this issue. They say there are 2 teams working on the issue. I wish them success ASAP.

I deal with this with a few finger sticks. And never make a hasty decision about my treatment,,, like what ineed to eat, insulin type and how much.

My old Libre 2 sensors that i uesd for a few years were pretty reliable. In fact the 90 day BGL report was a good prediction of my A1c.

Be well, pray for Abbott.

I use the Libre2 Plus. Someone gave me the reader and some sensors that her husband didn't use any more and I loved it. As much as one can love a device like that. I'm kind of a gadget/data nerd.

Eventually I persuaded my doctor's office to write me a prescription for the sensors. At first they were hesitant, like they thought I was going to sell them out of the trunk of my car to children on playgrounds or something. I pay for them myself. Medicare doesn't consider me "diabetic enough" to cover the cost. Whatever. I think each sensor is about $80. As you said, they now last for 15 days (just one day more than the old ones, so what's the big deal).

Since I've been ultra-low-carb/carnivore, the low glucose alarm has gone off twice! The first time I didn't know what the sound was, because I'd never heard it before. You know how it is, you hear a beeping and you look around-- phone? air fryer? clock? is it someone on TV? Then I saw it was the Libre2 reader. (I use the reader, not my phone--my phone already has so much cr@p on it!) My FBG was 79! It hasn't been that low in 30+ years. And then again this evening it went off-- BG of 70. I had a salmon filet for lunch and about a dozen sweet potato fries. Nothing else.

I endorse the use of a CGM. It really keeps you on top of what your BG is doing. Very important.
