I needed something for my kids to keep in their rooms that they could easily set themselves for time-outs. With this, all they have to do is turn their cube to the correct number and it beeps when they are done. I don't have to worry about setting a timer and they aren't yelling asking if their time-out is done anymore. I also use it to help motivate the kids for quick cleaning. I let them set it for 5 minutes and we see how much we can get done before it beeps.
