Best not to unpack and put in the display case (where the plastic stuff does not even look particularly nice). One reacted not at all to the inputs of the remote control. In another, the pressure-buttons have fallen at the first use in the remote control. The next time the wheels grind even their design the chassis. The next can not be steered. Everyone else does not have these problems, maybe can be max. 30sec. drive and must then return to the charging station. I expected for the price not much, but at least for one / two hours functioning toy could have been in there.
3 stars for educational value, as you can so show his children that cheap is not always good :-)
