Lets just say the "Bodygroom" is Shaft, Beanbag, and Starfish safe. No nicks or any pain...no worries...that does not mean go in there like a maniac...take your time...the two trimmers on the front and back(allow for push or pull stroke) knock down the forest while the foil on top produced nice smooth skin...Like any shaving product redness and skin irritation are inevitable (24 hrs later), however I noticed that the skin irritation was only about one third that of standard Mach 3 shave. The skin irritation was limited to the inner thighs (Shaft, Beanbag, and Starfish showed no signs of irritation)....Here is a word of warning, if you are a hairy man in the posterior / back (buttocks cheeks) region, I would not suggest going bald there...although the bodygroom does yield very smooth results, re-growth maybe a little annoying.
