Tide Buzz - Ultrasonic Stain Remover
The Black & Decker Tide Buzz Ultrasonic Stain Remover uses ultrasonic sound waves to remove stains from clothes before they are washed.

Consumer Reports says it works best on smaller stains such as motor oil, ketchup, lipstick and chocolate, but not quite as well on ballpoint pen, mustard and Cherry Kool-Aid.
