Total crap. Bought these to mount a subwoofer speaker grille to a vertical surface. He's actually sitting on a ledge/ledge, so he really just needs to keep himself from tipping over. My young children have broken all but one of the original pins over the years. He's been holding it well for over a year now, but I thought I could help him. Bought them for this purpose and they are literally the weight of paper. They offer ZERO help. Literally useless. At least I have less than $10. I seriously wondered if they would keep a piece of paper on the blackboard or in the fridge. He will hold 2 sheets of paper, three have started to slide. Any fan or rapid movement of air and even a piece of paper will fall. Find something else.
