The principle at Playmobil is obvious that the various RC vehicles can be "retrofitted" as required here and the remote control can theoretically be back and hergewechselt between different vehicles. But can practically forget that, since the installation and removal is so complex that we - once built - can be installed in the vehicle. Because of the many items you need to store the unused portions and find first time if needed and the (filigree) connectors also do not act as if they would withstand oftmaliges switch back and forth.
Then there is the as mentioned but very very steep price (currently between 40 and 50 euros !!) what a really absolutely expensive fun in conjunction with the certainly not cheap RC-enabled Playmobil vehicle draus (where the fun factor as already clearly described misses out, because the remote control do not really know what can).
Actually, I have to say this expensive price is already the actual main problem. For if the remote control cost "only 15-20 Euro", then I would let my thing indeed as "good concept" enter: because then you could easily be retrofitted all great Playmobil vehicles as needed with the remote control, and all these vehicles then use "parallel". But in its current form that would be just too expensive, thus making the concept simple little / no sense.
Thus, for me personally is actually a bad buy and I would not buy more, the remote control and can not recommend. Who the problem is aware they will afford and then also really wants to use in various Playmobil vehicles, which will of course make. Because the remote control functions, as stated in principle already. But just the purpose of this "post-Einbauens" and retrofitting just not clear to me and I personally would therefore no longer buy the device. For me personally, really just "1 star" (I do not like), but all in all appear to me "2 star" fair (in the sense of: "I do not like, but I can understand that some are satisfied with the device and find it great ").
