I thought three was pushing absurdity...
I then thought the vibrating handle was just plain weird...
Now I can't take the industry seriously with five.
I hope to ridicule any man seen buying a five blade sucker marketing gimick. Anyone dumb enough to buy a five blade is an just plain weak minded.
At Costco, 16 blade refills are $32 plus tax.
Vibrator in a razor is just rediculous.. but I do have to tell you, the Mach 3 blows any other razor I ever tried away.. there isn't a single or twin blade that can touch it... not only did the M3 have 3 blades, but they also changed the angle of the blades and gave them a cutting edge that nothing else can touch.
I thought it was all hype too when the M3 came out... but I got one free in the mail and tried it, and I have to admit, its better than anything else I have ever used... I threw everything else away... now not only is the M3 my primary razor, I've actually bought a few back ups so I have one in my travel kit too.
Don't knock the vibrating blades. They turned out to be a great product. They don't shave any better than any twin razor, but the vibration really makes them clean much more quickly. Whiskers don't stay stuck between the blades.
