I don’t get it. I use disposable blades and get about 25 shaves per blade in the shower with soap. Cost me almost nothing. I shave daily and have a moderately heavy beard.
I had similar results when Gillette still sold the Sensor, those were great cartridge/disposables, since I graduated to things like the Mach 3 I’ve gotten crappy blade packs on a regular basis, seems like the blades weren’t even sharp. This was in a variety of conditions. Cold water while deployed, hot water while home station, in the shower, using creams or soaps. Ensuring the razor was exposed to air to dry out, and so on. Same crappy results. Everybody’s mileage is going to vary when it comes to shaving.
That said, I separate from the military in about 8 months so my facial grooming will be a matter keeping a beard trimmed for the foreseeable future.
