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 ## Features - Waterproof - Using our guardian sensor tape you are free to swim and all the water activities.and can last up to 7 days or 7 times showers - Easy to Use - Perfect Shape Fit on guardian devices 3 and 4, Pre-cut back paper for easy to use by yourself, no need other help - Hypoallergenic - The guardian sensor covers are latex-free, not irritate your skin or cause any itching or discomfort.Suitable for most people and leaves no residue on body parts - No Sticking in the Middle：No sticking on the sensor for full protection .
