Review (2/5): Will not work on coarse hair, irritates sensitive skin.
I'm not very hairy, but I do has coarse hair. I tried this stuff on my chest and abs because I was tired of shaving. This stuff says it works on anything south of your neck, but after twenty minutes, it didn't even dent the stubble. Instead it irritated my skin, I look like I slept in a pile of fire ants. I followed the instructions, this stuff simply doesn't work on coarse hair.
If you only want something for your balls, this stuff should do fine. Any other area, stick to shaving, pay some one to wax it, or buy yourself an epilator.
