We had one of these going inside a movie theater for a playing of the old JAWS movie. People LOVED it. It motored around the theater, above their heads, and dipped and "swam", waving the tail. The only reason I don't give it five stars for quality is that you can tell it's blown up with helium because of the crimping on the edges. It's a lot of fun in low lit environments though. Worth the price here.
