Honestly, the Remington D-4444 Protect & Shine™ Shine Therapy Dryer is a splendid idea. For Remington. First you sell someone a hairdryer for around $54 and then every couple of months or so you sell them a refill cartridge of water with some vitamins in (A, E & D) for around $15. The cartridge sprays a fine mist as you dry. Just what we all needed. Oh, and just don't think about all those cartridges in the local landfill.
