4 batteries Mister Ocean and c is a party. (Convenient as mobile and wireless). C is stunning, the "blue wave" effect, as on the demonstration photos, captivating for large as for my little ones. More and c is quite magical: no noise! What is essential for a Zen effect without engine noise! In the end you wonder how it works?!?! Returning to the bluish effect on your ceiling. It's powerful and comprehensive. (10m2 ceiling without bp)
It works perfectly for a beautiful effect. A great gadget for your Zen and romantic evenings or baby amazed! I Recommend :-)
