Purchased this as a gift for an adult who flies RC helicopters. It was a huge hit... at first. But the car only lasted a few weeks before it was toast as speed control is dicey on an iPhone - the thing is really fast! As an earlier commenter suggested, a joystick controller may work better. But that takes all the fun out of using it with an iPhone which why I bought it in the first place, so I'm only giving it 2 stars. Needs better speed control.
I only got this becaue it was on sale. It is not worth the full price apple charges for it. I was also skeptical about the bluetooth experience given its potential for a short range, and my scepticisim was justified. The range is very minimal, good for indoor use and outdoors in a small area. You also need to go into the Bluetooth settings every time you want to play with this (but that may be the way apple handles Bluetooth). The UI is nice, but is not designed for the iPad, you need to go into 2x mode, which degrades the graphics.
