Q: How many shaves is this package good for? How many shavesvper cartridge?

I have been using mac 3 for since around 1999-2000 approx. The blades last me around 6-8 shaves before start loosing sharpness, I start feeling the pull and start getting irritated, that's when it is time to change the blade. You can use it as long as you want to but it will not be comfortable and instead one or two passes, you will have to do several passes which irritates your skin. I have tried other blades, even with the 5 blades, I don't like them because they are too wide and wont reach down to cut under your nosed, but it all depends on your face and how thick is the hair. For me the Mach 3 still the best
