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

[Jane Ferguson]

I just checked the cost and the FreeStyle Libre 3 is $40.00-$45.00 cheaper
per month in my area at OTC prices.
They did recall some faulty sensors if you look on their website.
Sincerely,
*Jane Ferguson*
