I use Harry's Razors...when I bother to shave that is, which is usually when the wife badgers the crap out of me and says I look like a street bum. I like 'em, as much as one can like dragging a sharp blade over one's face that is. They have a deal on their website where you sign up and they send new blades automatically. Me likey, easy and convenient.
Oh, and FYI, I am a MAN and my wife is a WOMAN. Nothing complicated, just a plain old male and female of couple of the heterosexual persuasion. We find that works for us. YMMV.
ditch the service and get a wet shaving setup. Cheaper in the long run AND a better shave. The 'more blades is better' stuff is hogwash marketing. A double edged razor is the way to go
