I have been on a 770 with the integrated guardian 3 sensors since February 2020. I first tried the sensor in my are with little luck. My numbers were inaccurate especially on the low side. I then tried in in my thigh with the same outcome. I moved it to the inside of my calf with much better results. I can’t believe how close my blood sugars have been to my sensor. I was going to give up but really happy that I stuck it out and kept trying. I can hardly wait for the 780 and guardian 4 sensors.
