Easier to use than the 3M strips, no waiting required. Just stick and go! Edited a few months later: I changed my review from 5 stars to 1 star. These do not work for long term. All the laminated wall maps I hung with them eventually fell, even when I doubled or tripled the number of sticky squares. And where I have tried to reposition (if it hasn’t fallen) after being up for a few weeks, it peels the paint from the wall :( maybe these are only intended for short term? Like a couple of days?
