We moved into an older house, we were always used to stud walls so hanging things in a house with all hard wall was a challenge. I saw the Takker after hunting for masonry nails. Dubious at first as I’d never seen one and seemed too good to be true. On receipt of the Takker, my partner wasn’t sure but total game changer. Pictures, clocks, even surround sound speakers are up on the walls now. Easy, minimal mess, recommend highly
