We bought this toy for our 4 year old son and he enjoys playing with this. In fact, one of the neat features of the Bakumat is that you can fold it and place it in a circular pouch. This makes it easy to bring the Bakumat when you travel. We actually brought it with us on a recent trip and the kids on the trip enjoyed playing Bakugan at the hotel room. That kept the kids occupied for quite some time and gave the adults a chance to relax.
The pouch is actually big enough to fit the Bakumat and my sons 20+ Bakugans and cards. That makes organizing the Bakugans much easier and prevents them from rolling all over the place.
However, the Bakumat feels like it can get deformed pretty easily. It's basically a circular wire covered by some cloth-like material.
