+ Very easy to assemble by fitting together the individual tracks.
+ The ball due to the "closed" tracks not fly out.
+ The racecourse can be assembled into various tracks and can be extended.
- The supplied ball hung constantly fixed on the train, because this probably is minimal too large or the ceiling of the train is not meticulously crafted. Can, however, overcome by the illuminated balls slightly smaller.
Quick accessory:
The Massage Center is leather hardly used. When I fill the included catnip into the opening, it is interested my cats just 2-5 minutes. The lighted ball, there are unfortunately only in a set with 2 balls and the price is a bit high in my opinion. The batteries can not be exchanged, unfortunately. Thus, a disposable product, when the battery is empty. Very bad!
Nevertheless, my cats love the ball. This is due to its slightly smaller diameter in a better path than the original ball and the lighting is also interesting for the cats.
The cats can easily deal with the racetrack itself. However, it also makes a lot of fun to play with three of the Cat Carrerabahn.
