loco fast

Beautiful esthetics, it makes sounds, it holds the road well and especially "it goes very quickly," as my little son. Significantly faster than the red loco of the same model yet, why? no idea. It is easily stopped with the middle button, and can travel only if one disengages. Obviously I advise to invest in a charger and rechargeable batteries, as the batteries wear out very quickly.
No negative except maybe the price.
