Attention-diabetics:

Don’t know if any of theses are the same type situation but they do issue warnings when there is a malfunction.

ALWAYS check the FDA site for any specific recalls - they are listed by product and S/N

FDA.gov 07/17/2025 - Continuous Glucose Monitor Receiver Recall: Dexcom, Inc. Removes Certain Dexcom G6, G7, ONE, and ONE+ Receivers Due to Speaker Malfunction That May Cause Missed Alerts for Dangerous Blood Sugar Levels

FDA.gov 12/02/2025 - Glucose Monitor Sensor Recall: Abbott Diabetes Care Removes Certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus Sensors 

So today, I must issue an apology to Dex Com. Wouldn't you know, the very day after I lost patience in not hearing from them, and posted the above, when I went to my pharmacy,THERE were more product, than the number  I had complained about, so Yes, Dex Com does indeed warranty their product, and I'm placing therm back on the "recommended" list, after all, their constant-read instruments are a big help in alerting to high & low glucose readings as they happen, so it sure beats sticking fingers four or five times a day, doesn't it? Apologies, Dex-Com for being too impatient !

Thanks for sharing your experience. It's frustrating when critical tech fails. For anyone else having issues, it might be worth checking the official Continuous Glucose Monitor Receiver Recall to see if your specific device is affected. Staying informed is the best way to handle these malfunctions.

Thank you for sharing your strory with all of us. I know how frustrating something like CGMs are as you have come to find out as well. I find it great when devices like Dexcom Continuous Glucose Monitoring System can be reviewed by their user.
