The strips don’t work...PERIOD. I’ve bought the small and medium strips. BOTH DON’T WORK. First of all it’s not damage free;  the strips ripped the paint off of my wall. They don’t hold up to the indicated weight and they don’t work. The adhesive on the medium strips are too weak to hang onto a frame and are useless. The small ones rip the pint off the wall.  The product is an absolute waste of money.
