When you plug it in the head spins (like a propeller).
That picture needs a warning message or a restriction rating or something.
Looks like it would chew on you like a hedge trimmer.
I'm out of here!
It certainly doesn't spin
As far as I imagine the internal piece of the head (the one with a visible wire or spring) that is to be put between the top element and the comb, oscilliates between two points while holding the blade.
In fact I'd like to try it out. Fortune favours the brave!
Unless it turns out to be a sweater shaver...
