Purchased a pack of these a couple of months ago. Cleaned the area on the side of our fridge with rubbing alcohol, left to dry, then stuck these on, pushing firmly and leaving for 24 hours before use. They worked great to hold a hand towel and a tea towel for several weeks, but one of them has slowly unstuck itself, twice. Upon sticking it back up it seems very secure as if it will never cleanly come off, but somehow it manages too! Shame as they look and function great otherwise. If the adhesive pad was better (perhaps a 3M one) it should solve the issue.
