Bests & Worsts Reviews from Amazon

We bought the Shark for my husband for his birthday. It took a little while to get here, but Amazon had told us that it did not ship, and when the vendor's new shipment came in, it shipped right away. It needs four AAA batteries. It cost $1 to have the balloon filled at Kroger's and then about 30 minutes or so to put it all together (We tethered it with a fishing line and weights and one of the kids held it while my husband attached everything to it). Be careful and follow the instructions to put it together correctly! Once it was balanced we were ready to go. It is surprisingly easy to control because it "swims" so slowly. All of us, kids (16 and 11) and adults, were able to use it well in a few minutes. It uses infrared so it works on line of sight. It cannot be used out of doors, even in near windless conditions - wind and drafts make it impossible to control, but it works beautifully indoors. It is obviously not a very sturdy toy, but with a little care (and if you have small children good supervision) it can last a long time. Overall a really fun toy, it looks and works just like shown on the u-tube videos.
