I use the Mach3 razor (original) for many years (even if men shaver is on it) and I'm still very happy with it. In the meantime, I have time to test for women, or the 4 or 5 blades, but I am always ended up with Mach3. Handling (small, narrow, flexible shaving), results and value for money are the Mach3 simply still best. Now I had the opportunity to test the blades for sensitive skin (sensitive). Unfortunately, or perhaps fortunately, I can not tell the difference to the non-sensitive blade. The shave is slight of hand, everything is nice and smooth, and modified or even negative skin reactions I also could not tell.
