Review: Great patches
Review: These have become my go-to now for my CGM. The adhesive works incredibly well, even after showers. And this is coming from someone who has tried quite a few at this point. The material feels soft like a bandage but not liek a fabric bandage. I have even had to cut one recently due to my placing mistake. I just knew that it would compromise the quality of the adhesive but actually, it didn't! It is still sticking strong. I usually replace these once a week, as that's when I replace my CGM sensor. There have maybe only been twice where I had to replace it sooner
