I am with the 5 blade system actually very happy. My face is smooth as a baby, no redness, and usually hold the blade at a daily shave about 4 weeks. Unfortunately, as a rule, because in some cases I had blades, mostly clustered in a package that does not really shaved only linking arms, torn from the outset by the hair, etc. These were completely useless. Oddly was referring among other precisely to the double package I ordered here on Amazon. Of the 8 blades I could use 3 pieces, the rest was absolutely useless. I'm going to be not of been eating from here plagiarism but that large variations in the production behind it. I had this kind of sound very pleasant even in the other, purchased in the supermarket packages, but then as isolated cases. The called for the product prices should already expect a 100% quality. I'm thinking back to back 3 "old" Mach, shaving is practically the same as a result, the whole system costs by half and to get there by narrower razors better access to his nose and other tight spaces.
