Time it with a cube.

Countdown to pretty much anything with Datexx Miracle Cube Timer. Just flip the cube to the right side and the countdown starts. There’s no programming required, just use one of the preset times – 5, 15, 30 and 60 minutes – and wait for the loud alarm when your time is done. It’s ideal in the kitchen, to time workouts or as a handy way to keep you productive in the office or while studying.
