Be prepared for what you buy [SEP] I have bought 3 of these over the years and I can attest they work as a charm. I have permanently gotten rid of my middle chest hairs and unwanted hairs in other places. It is also relatively unexpensive. The drawbacks are pain(no problem for me but if you are too sensitive consider using a xylocaine gel) and very very time consuming to do large areas. A trick I have found that helps lessen time needed and pain and scarring is take some instant glue and tip the tip of the stillet inside. After it dries use some tweezers to remove the glue from the very tip of the stillet. This way the currect will go only to the root and not the rest of the follicle.
