I think with the Brio labyrinth he had a knack. Had three generations and have fun at the game. If the ball disappears early, it is only the playful inability of the operator and not a defect in the device. Thus, thumbs up for the processing and handling. For our smallest (5J) the original path would be much too heavy, so the option of Auflegeplatten "light" and "medium" ideal for adjusting the level of difficulty and ultimately the game fun for all ages.
The in some reviews criticized "wave plates" we need to confirm, unfortunately. The first package, we had to return. The outer packaging and the game box were damaged (damage) and the Auflegebahnen were significantly distorted. Returns worked as smooth and efficient at Amazon and the new delivery then introduced us also satisfied. Even here the railways are minimal warped, but affects in any way to the operation and in deise extent for us is acceptable.
Overall I would recommend this game in terms of play value and usability. For but obviously existing variations in quality in terms of unequal warped Auflegeplatten there is an instant star deduction. Such a thing does not fit the requirements of a manufacturer like BRIO and is annoying for the customer who has the "hill and valley-Edition" caught.
Usually something so quickly solved via software patch in modern toy but we wanted to do something crazy times and buy something that just works so ...
