Give them a try. They are excellent and cost a third of what the Mach 3 cost. The Sensor 3 disposables have the exact same blade head but cost a few bucks more. So buying them is pointless. I've been shaving with the Blue 3 for a few months now (I still shave with my safety razors regularly) and they always give me an ultraclose and smooth shave, even smoother than the Fusion. I get about ten shaves out of one Blue 3. If more people knew about the Blue 3 quality, they wouldn't be blowing their money on the Mach 3 or Fusion.
