In turn encourage companies want "clients" supposedly more .... Now if we listened to them, soon the straight razors have blades that would cut 43 would overlap and hair ... no stop to it all up now only these "sensor" blades are really effective ... But "Gillette" still needs to earn more and supermarkets too. So razors to 3, 4, 5 blades that are less effective but the "pub" is mounted, and instead of 10 blades, 8 and 6 even fewer and more expensive course !!! Soon more than two sensor strips on the market, that's how "Gillette" is losing the "PERFECTION"
