Good but not fantastic.
This thing feels a little cheap but seems to work fairly well.  I use it only a couple of times a week so my hair can get relatively thick.  It takes time because the motor seems low RPM but it muscles through and does surprisingly well at not getting hair everywhere.  It does not get as close a shave as I would like and I generally end up touching up with the Panasonic electric shaver I use on my face. I think it is overpriced for a product that does a passable but not spectacular job (I expected a quicker and closer shave).  I am also a bit disappointed in the instruction manual with its microscopic font and illustrations, and the directions for removing the individual shaver heads for cleaning are poor (gently flex each head away from the center cutter and pry its cover off from the edge closest to the center cutter if you're having trouble). Still, for what seems the only specialized product of its kind, I'm happy overall.
