Am I the only person who gets as many cuts from an electric or a cartridge as I do from a DE, and way more irritation? I don't know how often I have heard that it is impossible to cut yourself with an electric, and yet I have. At least I know when I cut myself with a DE razor I just had a good shave. If I cut myself with an electric I still have patches of hair that the razor missed.
I had a plug-in Norelco with the two rotary heads instead of three. If you didn't position it just right or press too hard, it would leave semicircles of irritation. And yes, I cut myself (more like weepers) with it. Horrible on the neck, missed patches. Grrrr!
Maybe the ones with "three floating heads" distribute better over the skin.
