I used the Dexcom G4, G5, and G6. I found the G4 and G5 to be inaccurate. I find the G6 to be fairly accurate. I found the FreeStyle Libre 1 to be inaccurate. I found the FreeStyle Libre 2 to be more accurate than the 1, but not great.
Personally, I’m a T1 with hypoglycemic unawareness. So, the alarm feature while I’m sleeping is really important to me.
The FreeStyle Libre 3 was approved in Europe recently, which has a continuous reading with alarms like the Dexcom G6. It may be available early next year (2021) in the U.S. The big difference is that the Libre 3 will be affordable out of pocket. I have not been able to get Medicare coverage for any of my devices including test strips. They keep saying that I don’t have any equipment that uses test strips. Maybe it is because I live in NY. The Omnipod is not covered by Medicare.
What is your experience and accuracy with devices you have used?
