Rubbish
Started using Libre a few years ago and thought this would transform type 1 diabetes due to not needing finger pricks 3 or 4 times per day. Lately Libre 2 sensors are losing the signal multiple times per day and the readings given are just not reliable. Therefore I have moved to their rival Dexcom whose readings are more accurate and never looses the signal, so you have continuous readings and they are more accurate. I would advise anyone reading this to move over to Dexcom as their sensors are far superior.
