Hi Horlicks
I just put on my 3rd sensor yesterday, the first lasted 6 days before I knocked it off against the doorjam and the second lasted all of 12 hours and almost fell off, although I don't remember knocking it. Abbott kindly agreed to replace the sensor so I have now had the 3rd one on for just over 24 hours.
I seem to remember being a bit disappointed with the readings from my first one but they did improve and, apart from higher levels being high and lower levels being low, it was pretty much spot-on in the middle range, so I was happy with that.
The second sensor was pretty good, for the short time it was attached and working.
This 3rd sensor has been a bit 'off kilter' when compared to my meter readings but, again, seems to be getting closer. I'm not expecting the Libre to mirrow the meter readings but it's good to have it consistantly reading in line with the meter, even if I have to allow a bit on the higher / lower readings.
I understand a new sensor can take 24hrs to 'settle' before giving more accurate readings and that seems to be the case in my limited experience.
