Now, dont know how they will hold up in the AZ summer, time will tell. So far they have held. But on the package it did say to remove use heat from a hair dryer etc. I have read that some have used spray adhesive along with the sticky backing to keep them up. Cant speak to how well that works but would think it would survive the heat better, not sure about humidity.
