So the third and final shave with the mach this week has the cartridge starting to tug and take small bites here and there... no weepers but not 'irritation free' any more. As well there is a bump forming on my chin that is pretending to be something like an ingrown hair but might also be just a deep pimple forming. Let it be known this cartridge (orange mach 5 sensor) was not brand new at the start of the week and I forget how many shaves it already had but I would say maybe 2. So if my memory serves me 5 shaves and you are either going to start getting irritated or replace the blade. I was thinking to extend the experiment into next week using a new blue mach 5 fusion blade, the newer ones they say is even better to see how many shaves the blade gets before it starts to pull.

I am kinda missing the str8 though during this experiment and the experience of the shave is not at all the same. Kinda boring, generic, toy-like as others have said. I almost miss the sting of a good aftershave following a str8 that I am not getting with the mach.
