Alright, I got the Quattro the other day, and tried it for the first time this morning. I think the biggest negative is that it doesn't glide as smoothly across the face as the Mach3 does. Also found that I had to press harder with the razor then I would have to do with the Mach3. And I had to shave the same spot a few times to make it smooth, and inturn by shaving it over and over again it irritated my skin more. As for the design, better then past schick razors, but still doesn't compare to the Mach3. Mach3, so simplistic and easy to clean. Overall, it's the best Schick razor, but doesn't compare to Gillette's Mach3.
