Hi, I just got discovered this stuff on holiday in the US - it’s AMAZING! Instead of the usual 8-9 days I got 17 days out of my dexcom sensor (with sunbathing, swimming etc and without leaving any nasty marks on my skin)!!! You can get them on amazon but shipping to the UK is very expensive so I bought as many as I could get my hands on from Duane Reade and Walgreens… hopefully if i manage to get started on the omnipod the larger ones will help it stick as well.
