[Diabetes-Talk] Which of the two accessible CGM is better and why? Getting ready to meet with my doctor about re-authorizing a CGM.

I think it is misinformation to say the Freestyle Libre is less accurate. Unless you are a scientist and have done your own studies and can prove to me without a doubt that that statement about accuracy is true, I respectfully ask you not to put it out on the list. 

My Libre numbers correlate with my A1C's and my finger sticks in ways that have shown me that the product is accurate. You may like the Dexcom better, and that is your right, but for those of us who use the Libre and have had very positive, good results with it, we would appreciate not hearing those kinds of statements. Thank  you.

Libre replaces censors, but they, like Dexcom want to make sure people are  not abusing the privilege of getting a replacement. I have never had a problem.

Does anyone know of the Libre 3 cgm replacement policy?
