Thanks for the input. I think I'll give the girl a whirl... and let ya know how it works out.
I woulda been skeptical about this too. See... when they first came out with two blades (revolutionary!) all the advertisements showed some cheesy computer animation of the blade going over some stubble, with the narration being something along the lines of: "The first blade gets right up to the root, practically under the skin, and pulls the whiskers up, while the second blade comes along and chops 'em off".
So when they came out with three blades, I'm thinkin' that if one's doing the pulling and one's doing the chopping, then what the hell is a third blade gonna do besides give ya a clean close shave by way of removing several layers of skin?
But the Mach 3 turned out to be a glorious invention, right up there with the Gutenburg press and Dr. Pepper. I became a believer. So... when it comes to this kind of thing, I gotta give them the benefit of the doubt.
I bet they hammer ya with the cost of replacement parts though. That's how they always get ya.
