I don't know if it works, because I threw it away after one use
because it burned my skin so bad (literally for like 12 hours totally
red and stinging). After that I tried Kalo
(www.kalo-hair-removal.com), and after three months or so my unwanted
hair is growing much slower, feels much softer as opposed to abrasive
and stubbly, and there is definitely less hair in the area.
Good luck.
