Bought to help align loosening laminate fins (somewhat mysterious after being fine for more than four years). My floor does not have a perfectly flat surface (small but noticeable "ripples" in texture). bottom to look more natural) but the suction cups will grab and hold. Easy to use - still holds on even when the suction cups get a little muddy from the floor. I didn't need a rubber mallet, but other suction cups were about the same price and had lower reviews, so. what the hell. a spare rubber mallet never hurts.
