This simple device is easily operated by remote control and allows children to self monitor their behaviour.
Set the task time, 5, 10 or 20 minutes, the red, amber and green lights will indicate how far through the task you are.
Requires 3 x AA batteries and the remote control requires 2 x AAA batteries.
Lovely item. Daughter needed a replacement for one that was broken
Was surprised by how many batteries it needed! Both AA and AAA.
