Have tried everything: Gillette Sensor, Sensor Excel, Mach 3, Fusion from Wilkinson I've tested the Hydra with 3 and 5 blades. For me personally, the Wilkinson Quattro Titanium are sensitive the absolute best blades. These are my reasons: - Schrafe blades the rel. last. I have very tough beard and bad blades wear out very quickly. Then the blade moves only while shaving the hair and it is fearsome. This is different in these blades. They are made to last and are very sharp. My big disappointment were the Gillette Mach 3 - absolute disaster. - I cut myself quite often while shaving. Whether that's my clumsiness, I do not know. But the fact is that these blades thanks to the vertical slats are much gentler and I actually manage without cuts to get away! Disturbing I only find that the 4 blades (like almost all new blades) are very broad. Ie there is a relatively wide razor with which one moves through the face. I would go with 2 or 3 blades want to turn schnal and with which one can shave skilful. Why the provider not do that is beyond me. The 2 and 3 blade solutions from Gillette (Sensor Excel and mach 3) are very poor and hardly cut. I suppose that is so intent to buy the breteren and much more expensive blades. In any case I'll stay with the Wilkinson Quattro Titanium sensitive and can recommend everyone try the blades times ..
