I use the MACH3 for years now. Since I use the MACH3 belong to the bleeding cracks in the skin of the past. Even if it has to be fast and morning pulling the blade without much attention on the skin, the stubble are safely and gently removed without irritating the skin in order even carelessness tear. The blade lasts me a few weeks before you need to replace. Too bad the Gilette adjusts the model. It is my absolute favorite. Quickly strike and mount with blade.
