From Red-Dot:

DEWS is an upstanding toothbrush that incorporates a weight within its rounded handle base to keep the bristles away from dirty surfaces.

DEWS does away with concerns about whether your toothbrush is resting on an unhygienic surface. This upstanding toothbrush makes use of a weight at the end of its rounded handle to create a centre of gravity at the handle base. When the toothbrush is set down, it will sway momentarily until it reaches a position of balance – much like a tumble doll.  DEWS has been designed with ergonomic considerations, and its weight allows for comfortable brushing.
