I am assuming the blades in the disposables would be like the Feather blades some rave about on the 'fourums'... I have never used the Feather blades myself, but this looks interesting.
I am one of the members on another forum and I tried one of these Feathers. My face looked like hamburger when I was done. I normally shave with a Str8 and have no trouble, but the Feather kicked my hienny.
