A couple of years ago reading on the forum about all the problems some people were having with the Libre I thought no way I'll stick to the trusted finger pricks 6 - 10 times a day , last may I was offered a Libre at my annual review and can honestly say it's been brilliant , In that short time I've gone from using a reader and my phone as a flash to now a CGM , I can now see errors that I must of been making for years and rectified them , I've only recently had one sensor failure and after about three days got a replacement from Abbott their customer service was first class and never had one come off even after swimming, saunas , water chutes at centre parc last week so all in all I would say their brilliant and can't imagine ever going back .
