OHSO gets my nod for the most stylish and futuristic toothbrush/toothpaste contraption on the market today. The toothpaste is self dispensing and easily refillable by turning the handle one direction which creates a suction, bringing the toothpaste into the handle. There is a nozzle below the bristles that delivers toothpaste by turning the end cap the other way– and of course the top is a watertight cap which doubles as a rinsing cup. This is the MARKO model, but they also have a more feminine model they call DIVO, and another swanky model called the PRESTO. A movie accompanies the site showing the OHSO in action, which is helpful.
