To make it short, my kids love the aquarium! The design appeals to the kids, colorful fish, brightly lit round in circles. Unfortunately, the processing is very cheap. After a week of sporadic use of the fish slide had breits solved at the ends, because the lamp behind the film heated selbige and ends were connected only with adhesive strips. My husband stuck a makeshift lamp. What a real aquarium is very close, the volume of the lamp in the on state. The already comes the sound of a aquarium pump but very close :), although this was certainly not intended by the manufacturer! When falling asleep or staying Nachtlich I would therefore not recommend.
