I have a Norelco Body Groomer. It works well dry, not as well in the shower. I usually only break it out when I've been lazy for awhile, because it's great on longer hair. It "leads" with a trimmer before the razor part, so if my chest hair has been growing in, it'll take the longer hair down and then shave clean.
But when I'm maintaining regularly, the old Mach III does the job better. So in the shower, I shave head face chest and arms with the the same razor.
