Any diabetic can confirm for themselves my claim about the Dexcom G6's unacceptable persistent error states. Simply compare the CGM with your glucometer (testing 8x per day, for example), and watch the CGM go wrong (and stay wrong) on day 5 or 6 of using the sensor. I wish what you said was true. I would love to have a CGM that works better than a glucometer, but they don't exist yet. In particular, the Dexcom G6 is inaccurate in a harmful way.

I’m T1 and I use the G6. I used to regularly check against a glucometer multiple times a day (without calibrating) to check accuracy, and found no issues. A blanket statement such as “the Dexcom G6 is inaccurate in a harmful way” is certainly not true in general, even if true for you.
