I have only shaved ONCE with a cartridge razor. In HS, I used a Bic disposable until I grew a beard, and then kept it until I came to Japan. Then I bought a Braun electric to shave it off (not so bad really, just boring as all heck). Once, when my electric was broken, I tried to use a cartridge but it was so terrible I gave up on it.

Then, last year, I started using a DE and now I'm trying straights. Soooo....nope, no cartridges for me.
