Ok toy but disappointed by the "magical areas"

The rails are of good quality, when the circuit is mounted it does not come off by itself by the child's clumsiness (by cons for a 2 year old elements require too much force to snap and unsnap, so it's the adult who must build the circuit).

By cons, where I was pretty disappointed, is that "magic zones" only work with any of 6 vehicles tut-tut cars that have my son (fire truck, ambulance, tractor, concrete mixer, City, helicopter ) Maybe I of older vehicles models? But I bought the spring of 2013 on Amazon, so it really does not take long I think the manufacturer should provide clearer information about compatibility!

So, these "magical areas" not only do not work, but in addition have the effect of "back-d'ânes" that slow glide of cars, because going over the car's wheels touch while longer track and plastic from the underside of the car scraped against them not back-d'ânes nice to roll cars (while it's still the goal of a circuit), and it is because of that and lack of compatibility information that I put only 3 stars.
