EZ Fill Liquid Level Alarm - Pour Your Coffee in the Dark
The EZ Fill Liquid Indicator is a small bright red device that buzzes to indicate a liquid has reached about 1 inch from the top of a your single serve coffee cup, or whatever container your choose to use it on. Meant to help the visually impaired, we think it would also work perfectly for non-automatic shut off Nespresso, and espresso systems. It uses three 1.5 volt LR44 batteries (included).
