I have a PedEgg, I like it enough. I bought it at Walgreen's. I will buy just about anything from a store that has a good return policy. I just recently bought the Smooth Away and like it. So far, I haven't had any ingrown hairs, but I've only had it a week, so I'm just smoothing away and keeping my fingers crossed. ;) It won't replace my razor, but it's a nice quick, waterless (and razor bump free) way to "shave." :)
I will probably try the ShamWow, now that I know you can get them at a store. :)
