Dual Sound Liquid Level Indicator

Never again worry about over-filling your beverage glass or coffee mug. Hang the handy Dual Sound Liquid Level Indicator on the lip of your cup, drink, or mouth and pour with complete assurance.
When filling a cup/mug, you will hear a series of warning beeps telling you to slow down as you reach the top. The sound shifts to a continuous tone when the top level is reached, indicating the cup is complete and you should stop pouring. Pocket-sized, 2-5/8" for easy storage and portability. It uses one 9-volt battery (included.)
