Should last longer on your body
Work well just wish they stayed on my arm longer. They start pealing up around day 6 and my CGM is good for 15 days. So I have to use two per device, that is a wast.

Amazing!
Fantastic product only one out of all the products that sticks on my skin, very durable under water and in the heat, very effective, has a good stickiness to it, great value for money

ALLERGIC REACTION AND PEELED
Made my husband’s arm break out in a rash. It was also very itchy. It did not hold up for even one day, but immediately started to peel up around the edges, exposing the sensor to water and the elements. This was also extremely difficult and convoluted to apply. I don’t recommend purchasing.
