Norelco QP610/80 OneBlade Replacement Blade Body Kit

This is the kit you need if you're going to use your OneBlade on your body, especially on those sensitive areas. The flat guard absolutely prevents nicks (as far as I can tell).One drawback, that has nothing to do with the kit. Body hair tends to be thicker than facial hair, as far as I can tell. Using the blade on body hair will dull it quickly and, as we all know, the blades are far from cheap. Just be aware of this before you buy. There are other solutions for body grooming out there that do not eat blades.

I use mine twice a week and I don't replace them until the thing starts turning green. Make sure to use the top and bottom of the blade when you shave otherwise you'd be wasting half of it. Also use the green coloring as an indication only, sometimes you'd notice you don't really need a replacement just yet and avoid water as much as possible
