Say When is an audible liquid level indicator designed for individuals who are blind or deaf blind. In order to prevent overflow of liquids, it signals when a glass, cup, or other container of liquid is filled to within 1/2 inch of the top. The device is hung over the lip of a container with two prongs on the inside. When liquid reaches the prongs, a buzzer sounds and the device vibrates. POWER: Uses one 9-volt battery.
