My new razor and blades arrived today in a nondescript box, I was wondering what I had ordered, once opened I remembered that I had ordered a new shaving system, so, down to my man bathroom and a trial run on the five o’clock shadow. The only difference I can tell from this shaving system and that of the Mach 3 is that you have to run the razor over your face much slower, and the potential for nicks and cuts are much easier than with my old razor. Overall, I am very satisfied with my purchase and I will only use my former razor when I am in a rush.
