Used this twice so far and I gotta say I kinda like it. First got this cause my neck thinks I'm black, so I get razor bumps like crazy under there. Anyway, shit STINKS but it works well. You have to take the instructions serious as a heart attack if you don't want chemical burns.
I hear that it's also great for legs, pubes, et al. I'm looking at you, pub.
Basically, it's do-it-yourself Nair, and you get to 'shave' with a spatula afterwards. It's so ghetto that I feel 50% more manly every time I use it.
*it's also like $3 for a tin that has about 50 uses, lol
