This sleep training alarm clock is so very cute, but beyond that it is a great tool to have to help teach your child about bedtime and wake up times. 
This was very well packaged, the puppy is so cute and this runs on batteries or the power cord which is included. 
The instructions are clear making this super easy to set the different alarm features, and while the battery compartment will require a screwdriver to open the hidden parent panel does not making it easy to access for adults. 
If you have troubles there is a link provided to an online instructional video that is extremely helpful. 
I had this up and running in 10 minutes and the kids love him. [This review was collected as part of a promotion.]
