Title: Not a Good Deal
Review: These cartridges work just fine -- for about a week. Then the red light comes on. They're supposed to last for a month or so, but they sure don't last that long for me. I wish I'd bought the razor alone and forgotten about the cleaning system. It would be fine if these cartridges worked as advertised, but $3.33 for a week of cleaning is ridiculous.
