The Big Red Rooster Sleep Training Alarm clock for kids, has some great features.  My 5 year old daughter loves having this in her room.  She had a habit of getting up way to early, and now with this alarm clock, she'll actually stay in bed until the ball changes to the green color.  Very easy instructions to follow, wasn't difficult to set up.  Has 2 alarms, and a nap timer.  You can use the AC adapter which is included, or you can use 3 AA batteries.  The design with the dog is so cute, and my daughter thinks now having an alarm clock in her own room, that she's a big girl now. [This review was collected as part of a promotion.]
