I signed up for the cornerstone subscription service just as they were moving from the old style blade to the new blade. My first package arrived with the old blade and I was really pleased with the shave. Unfortunately the next package arrived with the new blades and are nowhere near as good so I cancelled my subscription. Happily I've found another subscription service that uses the original blades, I think they bought the German manufacturing company, and I'm back to a really smooth shave.
