This was exactly what I was looking for to help my 3 year old. I appreciate the large variety of options for different lights, sleep alarms, even brightness of the colored ball...ect. You can set alarms, and choose if you want just color or noise. You can set multiple alarms at the same time. The only change I would make...is when an alarm is set; the dogs ball is red. It would be nice to have the option for the ball to be off until the alarm, at which it would turn green. [This review was collected as part of a promotion.]
