I’m having issues with these new Sensor 3 sensors I’m using with the 670g pump. I love the pump, I also love continuous glucose levels. My mayo nurse never put me on auto mode, so I’ve manualled it for the last 6 weeks and my glucose levels are generally in control and the low suspend is outstanding. The problem is with these sensors. Sensor 1 lasted 3 days, then goes into a 3 hour ‘update’ and tells me to replace sensor. Sensors 2 and 3 lasted 7 days, great. Sensor 4 lasted 5 days and 11 hours, same thing, ‘updating sensor’, 3 hours later fail and recommend to replace. Sensor 5 lasted 5 days, 11 yours, ‘updating sensor’ for 2+ hours (uh oh!) and then surprisingly worked fine to the 7 days. Sensor 6 lasts again, 5 days 12 hours before the ‘update’, and replace sensor there’s a pattern? Lovely, it’s $800 for 5 of them through edgepark. Now to sensor 7, now this one bled where the others never did, but followed the troubleshoot on bleeding. Clearly something was wrong with the insert/user error or who know as the sensor took forever to ‘warm up’ but keeps indicating I’m low, where the blood glucose monitor says I’m high. Of the 7 this is the only one that wasn’t within say 8-10% of the monitor on calibrations. A recalibration and with the discrepancy… change sensor after not even 7 hours. Oh, speaking of calibrations, it often wants them every 6-8 hours instead of every 12 hours, and then sometimes at 12 hours which gets annoying trying to time it so you don’t get woken up in the middle of the night buzzing you to calibrate. Sound familiar to anyone else by chance? It always could be user error, I’ve spent an hour on the phone with medtronics and more than that looking up solutions on line. Frustrating.
