Glad to hear it worked for you. The roll should last forever but I would say next time maybe get the 4" :)
I noticed that the G4 adhesive does not stick to me at all! I had the SEVEN before and it sticked to me great. Either my skin changed exactly when I upgraded to the G4 or the adhesive is different on the G4. The edges start to roll within 10 minutes of putting it on my body….its ridiculous. I am going to call Dexcom on Monday to see if they heard of anyone else with this issue. Its a drag to have to "tape" it on my body right when I put it on. Not happy!!
