Hi there, I'm new to diabetes: my son was diagnosed 6 months ago. What with GCSEs and him getting his head around it, I am supporting him quite a lot (trying to). We had a trial of the Libre early on. Poor chap has eczema and all that hand washing was making it worse, as he was very diligent about finger pricking. We have found it to be amazing and we trust it as much as the blood meter now. When you have a dodgy sensor, it is obvious almost immediately, as the readings are (in our case) significantly higher than they normally are. A finger prick confirms this and we change the sensor. We found that most of the readings are either spot on the same or different to about 15 mins behind what the blood readings are. That's actually correct. The extremes are less accurate - outside of about low 3's to 9. The first day is inaccurate, so we now cross over and wear the new one for a day before activating and this has resolved the issue. My son wears his on his thigh. You're not supposed to, apparently, as it's only licensed for the arm or abdomen. But it works fine and is unobtrusive for him. You scan through clothes. It has made a huge difference in that you get to see the 24/7 picture which means we've been able to adjust things better towards very tight control. And his HbA1C has reduced significantly - I believe this is because of the Libre. I can't recommend it highly enough, personally. It's not cheap, but we would do anything we could to make sure our son has it, because it's so brilliant. I would like the alarm feature of the Dexcom, but it just looks so huge in comparison - I wouldn't fancy wearing that myself, but the Libre is small. One thing to watch - I ordered 10 and just realised yesterday that I have 5 left that expired end of April. They wouldn't allow me to return them as it was more than 28 days from purchase. I asked how they thought I was going to get through them all in time - i.e. within a couple of months only - and their view is that they don't know how a buyer is going to use them (?) So just watch for that one.
