With the cover on the lights it turns to a cosy nigh light, but with the cover off the whole room becomes an open space as it projects planets, galaxies & stars. It is also could be useful for romantic occasions especially with a nice music.
The light includes a USB adapter that can be plugged into any USB hub, port, we always have a few spare ones. As an option it can be used with 3 AAA batteries. I think it's a great present and a quality product. Probably not the premium product but for this money it's definitely worth it, for sure!
