This has 2 projection theme modes star sky and sea world theme can be changed. Install one of the two films, which can project various patterns included jellyfish, sea horses, dolphins, clownfish, starfish, algae, shell, conch(Sea World Theme), stars and moons(Starry Sky Theme). Remove the inner two films and close the top cover, it is also a little bedside night light. Has 8 color light modes warm white, red, blue, and green LEDs project 8 colors light, nice different patterns make you feel like staying in the middle of underwater or becoming a star rover, it all depends on which projection theme you are using.
The projector lamp could be 360° rotation, either you want it to rotate dynamic or become static, it can offer you an amazing and vivid vision. There are 3 buttons on the front side of the night lighting lamp, you could choose different color displays, light rotation and light mode. The projector lamp can be powered by 4 AAA battery (Not included) or USB cable (package included).
My Opinion: I like this and it is so relaxing watching the stars on my ceiling at night unwinding after a long day that can be busy.

This is a Tomoson Review which I got the product for free or at a reduced price but just because that happened does not mean I was swayed to give a positive or negative review.
