I really like these. A little difficult to apply. Stays in place for 14 days. Does not leave dark spots or residue when removed. Small amount of fraying around edges around 12 days.

I live in a location that gets 100 plus temps is humid and hit by two hurricanes in last 2 weeks.First I say overall my rating is good and like a B+ but the useful stuff to other is why not A+ so here goes...It surprisingly comes with many small packets of skin barrier for sensitive skin people I don t need it but must be huge deal for others.The small Cons were the backing that you peel off the back before applications has 4 pieces and can get goofy trying to get all 4 pieces off by yourself. Needs to be easier.And I think because of this one spot always seems to not lie flat from day 1.But so far they have all stayed attached to the end and that IS THE POINT.I haven t had any fail completely within the 14 days.Actually I try to go 3 to 4 days without an aftermarket patch then allow the aftermarket to keep the sensor attached days 4 through 14.Works as I expect an aftermarket patch to work

Doesn t stay on. Off after just one day.

I bought these for my husband. We live in Tucson Arizona and it is 120000000! degrees outside and my husband sweats. He had lost several CGM s because he sweated them off and was also afraid of going swimming. I tried some of the clear covers and used skin adhesive to put them on but they did not work they just rolled up on the ends and became ineffective. I bought these and glad I did he has not lost one CGM since he started using these. They fit the G7 perfectly. They do ravel slightly on the ends but they still maintain their integrity. He was at the point where they would not replace anymore G7s and we would have to pay for they out of our pocket..so in reality these have saved us literally hundreds of dollars.
