It is a great tool, it has up to 24 alarms, that can be set to go off randomly or at fixed times, it vibrates silently in the kids pocket. When it vibrates they ask themselves if they are paying attention to the teacher and doing the classwork they are supposed to be doing. It "wakes" them out of daydreams. They can self-monitor themselves, and can also set additional alarms for reminders for those who are also forgetful. I would recommend this to parents who have daydreamers or forgetful kids. Also a great tool for diabetic kids, to help remind them about blood checks/insulin times.
There oughtta be a similar device to remind teachers to stop boring kids so they would rather learn than be somewhere else.
