Its electronics are problematic. It has 2 electronic parts that need to "pair" in order to work, and really sometimes they do, sometimes they don't, in other words, it works when it wants to... Also, it could be more functional, for example, the ladder could open, or the vehicle could turn both right and left (it only turns towards one side). It has nice plastic quality and a beautiful idea, but the execution is quite poor and problematic in use.
