please note that the original statistics quoted came from gillette themselves...

thanks,

I looked at all that now, and I have to say that the original way of arriving at the 4 weeks was, to say the least strange. But the fact that all these guys said they get 4 weeks is mind numbing. Besides, I wouldn't trust anything Gillette says without a detailed look at how thet arrived at it.

I have tried every cartridge that Gillette has ever sol in this country. Never has one lasted more than a week. I have very sensitive skin, s it limits my use, but I can't imagine getting that much longer use unless my skin was like leather. And that aside, it just doesn't cut, and my hair is fair, fine and soft.

The only way I could see it happening is if these guys were taking one pass shaves.
