I don't understand why people use disposable razors. I own an electric shaver and it lasts forever. Replace the heads about once every 2 years, for about the cost heye pays for a 12 pack of his razors, and good to go.
Plus they are way better for the environment...not all that waste going into landfills. That's important to me.
Oh, and it's a helluva lot easier to shave with an electric razor.
