Bought this based on the ads and that they last a long time for a good price. The first blade that was already on the razor was good, but the rest of the cartridges didn't last half as long. After replacing the blades so often, I realized that this is no value and that either I got a bad batch or they purposely put a good blase on first, then put lesser ones on to cause you to use more blades and make them more money. But, I will not buy these gain. Once burned, twice shy as they say. This was the "injured" Brett Favre, not the start quarterback who played for the Packers who is the company spokesman. In the end I felt cheated and went back to my Gillette brand razors. They cost more but I can rely on them and that's what I need.
