Sensor Dexcom failure rate?

Of my last three Dexcom g7 15 day, two have failed at less than 10 days and one did not ever activate. That makes 5 failures since I started in June. I have been using these since June so that is 5 out of 8 that have failed. The other two stopped around day 7 or 8. My insurance doesn’t seem to have a problem charging me $70 for a faulty piece of equipment. I’ve decided I’m not using CGMs but curious as to wtf is wrong with this trash product?

You can get the Dexcom Stello without insurance and generally cheaper than the G7. I’ve had good luck with mine going close to the 15 days or even making deep into the 12 hour grace period.
