This is a delightfully soothing and magical addition to the night sleep routine! It beams stars, the moon and a beautiful unicorn onto the walls and ceilings while also creating light for the little ones at night. It has multiple settings to create the right atmosphere and can be plugged in by USB cord as well. So no need to use up the battery life. My grandchildren just love it and get to bed early to have a little magical wonder before we decide on the right setting for all night…Having slept in the room as well, I love it too!
