Has anybody tried those Hercules Hooks I've seen advertised on TV for hanging stuff on the wall? They're basically thin curved pieces of steel that you shove through drywall that can reportedly hold up to 150 pounds. The guy hawkin' them is the same guy that sells the OxyClean and Orangey stuff, so right away I'm skeptical. But I have a lot of photos and stuff to hang on the wall, and though a bit pricey, these things look a whole lot easier to use and less damaging than using a bunch of wall anchors.
