This is a replacement head for a lower priced Remington shaver. I cannot even find these heads in department stores or pharmacies. Because the blades and heads come preassembled they are easy to use. Cleaning daily is simple and quick with a shaver brush and a can of compressed air like those used for electronics cleaning. I recharge my shaver every 4th shave and use Remington SP-4 Shaver Saver lubricant spray after cleaning and just before plugging in to recharge. I highly recommentd these 2 products.
