Perfect for my kindergartner!

This night light Bluetooth starry night projector is fantastic! This is battery operated so I do not worry about an electrical fire in my kids' room, and it is run by a remote control which I keep. This takes 2 AAA batteries that are not included, or you can use the USB cord that is included. We set this where she wants it when it is bedtime, and play some music to soothe her to sleep. It is absolutely beautiful with all the colors and stars on her ceiling and in her room. This is easy to use and operates well. I love that she is calmed down for bed, and she loves the stars and lights and music. It is a win-win situation all around!
