They do what you expect. The adhesive is quite tacky. Even after 10 days it was still on very well. Slightly painful to remove. I recommend removing while in the shower. The hot water helps release the glue.

I was using large Band-Aids over my CGM but they didn t last very long before they peeled off. These last several days before they even start to come a bit loose or fray around the edges and then they still manage to hold on until day 10 or better. I have sensitive skin but so far I ve had no reaction to the adhesive or material.If I could suggest an improvement it would be to offer a style with a small hole to match the hole on the Freestyle Libre 2 sensor. This (according to the manual) should be left uncovered for more accurate readings. There is a donut hole style available but it leaves the top of the sensor entirely uncovered. I tweak mine by cutting a tiny hole in them. It s not fair to dock a star because I knew this when I bought the patches but that minor adjustment would make a good product even better.

I like the patches. They are a little thin but get the job done. They also stretch quite a bit. I have had no issues with the adhesive.

Initially I was happy with the product. It does fit the Libre3 with no problem. However based on my day-to-day activities the cover fibers starts to peel off and then the adhesive about a week after. I also have a reaction to the adhesive as it becomes uncomfortable to wear. It would be okay if there is no skin reaction but there is. I would be looking for an alternative.

I really wanted to love this. I was looking for some extra protection during summer. I have used 3 times and each time by day 4 they peeled and started to fray at the edges. I cannot recommend this product.
