Guys I've been on the libre fr about 2 years now and the odd one plays up but last week but the last one has been waaaaaay out 16 when it figure tested it was a 7 always 3mml above a figure prick even if BGL is in range ans stable etc, so yesterday I too that one off a week early and swapped for a new one and again it's similar 3-4mml out in regular BGL readings, the one thing I did notice is that when the last two went in there was a slight tug whilst pulling away the applicator which never really happened before on the reliable ones/ May be a defective batch? They are both still date.
