Since my cousins are complete techies, the castle was still modified in connection ...
We have assembled a battery pack under the base of the castle. (3 x 1,5Volt with AAA batteries)
Then we have several LEDs built into the base plate. Now the castle and the walls of interior is illuminated. In addition, you can turn the castle exterior lighting at the edge of the base plate with a switch. The castle is then illuminated from below. To this end, we worked another 3 hours.
Conclusion:
Whether with or without illumination. The castle is definitely a chic part. The parts are stable and well finished and the printed ink makes a good impression. Chromatic aberration can not be identified. The included manual is also well structured and easy to understand.
Unfortunately, a lot of packaging material used.
Also, the point that Ravensburger is a German brand, but the product can be manufactured in the Czech Republic, I personally do not like. From me there's so 4.5 star ...
