Review (5/5): Slinky of Pain.  Hurts like a mother, but works really good.
This thing is awesome. yes it hurts, but no more than plucking, and you can grab a bunch of chin hairs all at once so the pain only lasts a nanosecond. It's harder on moustache hair because it's more sensitive and once it grabs on you are at the moment of no return and you have to go through with it and sometimes I cry a little but it really gets those dang hairs out of there. Much quicker than plucking. i haven't used any of the other things they put in there. Just the slinky of pain
