Good thing I got the freebie instead of going to grab a retail one to try out. This thing doesn't do anything for me. I think it might be the head angle but I can't get a decent shave at all. Back to the Mach 3 I guess.
I can't imagine that a four-bar would be at all good for legs unless you're some kinda monkey girl, and if that's the case you should consider an "adult" orientated career.
