The device has three metallic probes which indicate two separate liquid levels within a cup or mug. The first audible alert tells you when to stop adding hot water if you also want to add milk; the second alert tells you when the cup is nearly full.

The liquid level indicator can be used on most cups and mugs, as well as glasses, jugs and (cold) cooking pots.

Use the built-in magnets to store your device on the fridge door, so it's always easy to find when you need it.
