Bought a PedEgg but not directly through the commercial because I knew of the sleazy practices that way. Love the PedEgg! It really is a good product.
The only other product we tried was a huge mistake. Patch Perfect. It's supposed to be super strong grass seed that will work anywhere. We had patches in our backyard that would never grow and thought this would solve the problem. Nope. Followed the directions and just ended up with green slop sitting on the areas. Eventually, it turned brown and blew away/disappeared. Not even one blade of grass.
ETA: I just looked into the NoNo hair removal system that's heavily advertised right now. The reviews on that one are too much! Sounds like it burns the hair off, which leads to some awful smells and scorched skin. Definitely read online reviews before ordering any of these products.
