In short, the part that's amazing !!!
Extremely loud speakers, LEDs very bright and colorful, like at the fair.
Engines are extremely strong - to turn Turbo on wet ground by the tires!
Remote control works very well.
The two batteries last about 2 hours - unfortunately lacks a charge level indicator - no idea how long I should / must the car terminals to the power outlet.
All around a great section for children - not only perfectly finished in detail and the structure was white knuckle)
Highly recommended - for the money gets you nothing like it - especially not with 2 motors / 2 batteries.
