These things fly fantastically through the air. definitely has sinister shark moves. But it has a number of significant problems. The biggest problem is that the remote control is IR (infrared) and not radio. The result is a very choppy ride, limited to the line of sight of the shark's abdomen. Essentially, you have to be nearby to control it. Other issues are rather minor and mostly related to cheap materials (poor mounting points, etc.). For the price I was expecting that, so I'm fine with that, but I would definitely pay significantly more for a higher quality version that could last a long time.
