I'm just an occasional user of Libre.
With a holiday starting tomorrow, i put one on yesterday planning to start it up this evening
BUT as I got out of the shower this morning it simply fell off. They are usually like limpets on me needing industrial removal.
I called Abbott thinking I might be in for an argument as I hadn't even started it, but no problem. Nice as pie and licketty spit they agreed free replacement.
Good service
(Lucky I have a couple of spares so no.2 on and fingers crossed it stays on and working suncream and swimming will be involved)
