My kids (4 and 2) got these for Xmas. The 2yo is a bit young for them, but the 4yo can control his pretty well. Each controller has a colored tip on the end of the antenna so you know which one controls which car; it took me a day or two to notice that.
One tip: we had a hard time getting the little drivers to stay on their seats until we realized you can push the ejector button down to snap it in "ready" position. Learn from my fail and save yourself some frustration.
My work here is done. Pedant-man, AWAAYYY!!!
