Hi, not been on the forum for a long time. I'm now on prescription Freestyle libre 2 which is great, when it works. DN fixed the first sensor ..fine. Fitted the 2nd myself no problems. Fitted 3rd myself and it went into a start up loop, each time 60 minutes were up I scanned by phone app as usual and it went back to 'starting up new sensor' So after hours of this I took the sensor off and found the needle/filament was bent at a right angle. I assumed it was user error, my husband put the next one on and it was fine until 2 weeks later my DN phoned me to say she'd had no data from me for 2 weeks. There's data on my phone app. So today my husband fitted a new sensor as the two weeks were up and the blinking thing went into a start up loop again. Took it off and the filament is bent...again. Everything has been carried out to the letter. Has anyone else had this problem please? Are they just duff sensors? Abbott are supposed to be sending a replacement for the first one. Sorry to go on but I really thought this would be a game changer and I've waited so long for it.
