My Libre3 sensor went crazy after just 2 days. It was reading significantly high (+25 over finger stick) for about 12 hours after it was installed. Then, yesterday, it was spot-on when I checked it a couple of times. This morning it was claiming I had several lows overnight, but I don’t think it hit the alarm threshhold. I sleep with noise-canceling earbuds, though, so it might have. At about 4 this afternoon it started screaming at me and reporting glucose of 53. Finger stick was 86. That is *not* acceptable. Over the next 45 minutes, while I was on the phone with Abbot customer service, it recovered most of the way to an accurate number. Then it plummeted again. Dang thing was on a 10 minute loop and kept making the app scream. Abbot is replacing it, and asking for the two-day-old sensor back. How common is this type of misadventure?
