I need to install a floating shelf to hold my PS5 which is big and heavy. The problem was that the wall was some kind of drywall and the regular screws just drilled a hole in it and had no grip so they fell out. This item came to the rescue and I was able to just screw them to the wall and my shelf is safe! Great article. The only downside is that you have to be careful when screwing it in, as the plastic part of the screw can break if you use too much force.
