Freestyle Libre was my first CGM and as soon as I had the opportunity to switch to Dexcom, I did.
Each new sensor was wildly low or wildly high, with no option to calibrate. It was really only good for measuring changes, not the actual glucose reading itself.
So "Oh, it's going up, +5, +10, +20... probably accurate, but is it 80, 180, or 240? Use a finger stick to know for sure.
