Just moved from Libre 2 to Dexcom 1 and have found accuracy and reliability both to be with Dexcom 1. I've been diabetic for over 50 years now and blood sugar levels accuracy is essential for a healthy life. Libre sensors are around 2 points more than the Dexcom 1, so if your readings on dexcom 1 shows 7 then Libre 2 is 9, that's very inaccurate. How can you. Control sugar levels with that accuracy, shame on you Libre, hope you loose the UK NHS contract. Libre also looses the signal. Piece of pish
