Washed hands, tried all my fingers. Libre steady between 7.2 and 7.5. caresens now showing 10.5. so caresens feels high but libre feels too steady! Going to have breakfast and see what happens and then go and get new strips. Hoping I can get the ones to fit libre as if it is the sensor then that will give Abbott the info to hopefully refund the sensor. If it's the meter then lesson learnt re strips and their sensitivity to heat.
