My last sensor timed out this afternoon but it did last it's allotted life. I've still not received a replacement for the previous one that died so I guess that's the end of my experiments with the Libre for a while.
Stats are out of 6 sensors, 3 lasted the 14 days, 3 died (1 fell off, 1 stopped, 1 caused a big bruise). Then of 2 meters,the first had a button fail, the second is still fine.
Accurancy, I'm not sure. The first 4 sensors where all but useless one way or another, I could never believe or trust the scans The latest two, the first looked promising but I had to take if off after 2 days. This last one has been more than accurate enough for me - generally within 0.2mmol from a BG (usual qualifiers here) with the meter.
Maybe I got unlucky with an early production batch of sensors / reader.; just maybe the later sensors are better. I hope so but for now I'll let Abbott find someone else to carry on their field trials..
