Hi Jock
I started in the Libre when I was self funding, and found it very useful in so many ways. It is extremely useful when out for a day of walking. It works through layers of clothing (we were in the Dolomites at -25 C so I had six layers on and it still worked) and is so much easier than faffing with a test kit. I have also learnt a great deal about how My BG reacts to certain food, as well as adapting timings of insulin delivery to avoid spikes.
With regard to any problems Abbott have replaced the one I had that was very wrong (out by about 8 most of the time). I don’t worry about small differences between BG and sensor as they are measuring different things. What I want is the direction of travel arrows, in order to head off hypos or hypers, and the graph to help me make decisions about adjusting insulin doses.
If I am going to swim or off on a walking holiday (so a bit sweaty) I choose to put a tegaderm over the sensor (you need a hole in the middle to let it ventilate) just to be sure that it does not fall off. In two and a half years I had one fall out as there was no sticky on the pad. Abbott were brilliant. I also knocked one off but did not ask for replacement as it was my own fault ( well actually the door frame did it, all on its own!! There seems to be a problem that door spaces narrow as soon as you put on a Libre sensor, so I just play safe and use the tegaderm.
I hope that helps.
