They are very chunky though, and designed for face shaving. The Skull shaver thing looks more lightweight and more comfortable to use above your head.
$60 isn't a terrible price but I've never had luck shaving with an electric.
That thing looks cool, and I admit I'm curious. Gonna resist this time though. Electrics have never really worked for me, and I seriously doubt it can do as good a job as a HeadBlade.
I've tried Skull Shaver but haven't tried Head Blade. I normally prefer shaving with cream and a blade but when I wake up in the morning and see a beard coming I use the Skull Shaver for about a minute to quickly clear my cheeks of whiskers (to help avoid acme). If I tried to do that quick with a manual razor I may cut myself. If you go over a few times and press down firm enough it'll shave pretty close to the scalp. It's hard to move from traditional proven ways.
