Bests & Worsts Reviews from Amazon

I buy a pack of 8 of these (I shave 3 times a week), and each cartridge last me about two months. How? Go and buy a duster can, I get three of them at Frys for $8, or you can find them at any home office store. Every time you shave, take the duster can and dry the razor, including the strips at the top and bottom, pushing off any residue to the sides. Water seems to be the worst thing for a razor, yet using this technique makes my blades last for months!
