Review: The adhesive is long lasting. - Not easy to apply by yourself but if you have a partner/ friend to help they are great and stay stuck for 10 days or more.
Review: Good - it didn’t fit minimed mio advanced infusion set, might be my mistake as I assumed it would fit as the pictures show minimed 780g pump, however you just have to cut the circle bigger and then it fits and works quite well
