The MACH3 sensitive promise now an equally good result in better skin protection. Point 1 gets from me a clear 'yes'. The blades shave properly and leave a pleasantly smooth, neat feeling. The shelf life is up to me with daily shaving at 1-2 weeks which reported other benefits Month (s) are utopian for me and species in wüstem Geschubber from.
Gentler shave than the normal blade I can not confirm. As with the "normal" blades sometimes occur mild skin irritations that I could, however, so far with no blade system (also 5er) avoid them altogether. The frequency of irritation is thus at the exact same level as in MACH3 standard.
All in all, the MACH3 sensitive sound very good razor blades, due to the lack of additional skin protection effect, I would grab at a lower price to the normal blades. 4 stars.
