Bests & Worsts Reviews from Amazon

I bought 2 of these cars for my kids to race based on what I believe is misleading advertising. Per the Product Description on Amazon, "All models include the dashboard hand controller with multiple frequencies so two cars can be driven simultaneously.." I assumed that you could actually change the frequency of each car so they could be played at the same time. Not so! I called the manufacturer who informed me that you have to buy one car at 49Mhz and the other one at a different frequency. As such, I'm left with 2 kids with 2 cars that both are controlled by the same controller...not much fun for playing racing!
