Do you use the Phillips Bodygroom?

My wife bought me a Phillips Bodygroom for Christmas. I was really excited about it so I charged it for the full 8 hours (as suggested) and then jumped in the shower. I normally use a straight razor anywhere that I want to remove hair and I’m naturally not very hairy to begin with, so, for example, my chest hair was already fairly short (~ 1/8”), but it took me nearly an hour to shave my stomach and chest and it still didn’t get all the hair! Needless to say I was pretty disappointed. I’m going to give it another shot, but I’m starting to think I might be returning it. Has anyone else had a similar experience with this product?
