This is a great concept and my toddler loves his little watch. But, the product is not well made & proved to be uncomfortable for him to wear as it has a rubber wrist band.  Also, the one I bought stopped playing music after only a week!!  It was undamaged and just stopped working properly.  I kept it anyways because my little boy still likes the lights that flash, but it doesn't serve the purpose I bought it for any longer.
