We just purchased this toy when the Hot Wheel Cyborg Assault, my 4 yr old's gift from Santa, BROKE after a few minutes of (supervised) play. They were out of the Cyborg's so my son chose this. He is in there now calling it junk. It was confusing to assemble and the car will NOT stay on the track as it shows in the pictures, no matter how much you REV it. My son has a difficult time revving it without making it click, and then getting it on the track correctly is a trick. This one will probably go back to the store as well. I think we are done with Hot Wheels (for as long as I can get away with it!)
