I bought some blades for my old injector and used it for the first time just now and what they say is right, It's so easy, the angle is perfect just place the razor on your face and shave as fast as you want. It shaves like a modern razor but it's not as aggressive on your skin as a mach 3 or track 2 with all those blades. You can actually shave while in stupid mode, not having to think about anything.
