The key thing to recognize with modern Gillette cartridges is that the blades last a lot longer than the lubricating strips. For me, those lubricating strips last a couple of shaves at most but I get 15-20 shaves out of the blades. When the strip wears off the shaves get a bit uncomfortable while that stuff peels off but then they start to feel better again after that. A friend of mine actually hates the strip so muc…
I don’t want to risk sounding disgusting, I use a Mach III to shave my face…daily. Now I have a beard, so I don’t shave my whole face. Neck, cheeks … but I get 6 months to a year out of one cartridge on these. Having just replaced, I agree 100% about the lubrication strip.
On the other hand I experienced blades that were unusable or even oxidized after 2-3 uses.
