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.

If your pancreas is not making enough (or any) insulin, is a pancreas transplant in the cards for you? (I almost wrote, "in the carbs for you" 😄.)
My late husband (died 25 yrs ago) was a type 1 diabetic for decades before quick and easy glucometers were available, let alone CGMs. He had a kidney transplant in 1992, but of course, was still insulin dependent. Pancreas transplants were just beginning to be talked about. He did get an insulin pump, but it was probably pretty primitive compared to today's. I haven't kept up with medical news about that.

U go young girl @

Woo-hoo! This rings the loudest for me--bravo! 👍
Most people can't relate to this number (lucky for them), but they can relate to the number on the scale.
