It's very good... for two to three days...

After that, the animals have evolved into Super Bitzee and you have to format it and start over from the beginning.

It will keep the kids occupied for the first few days and then it will just decorate their desk.

45€???!!!

They aren't worth it at all.

I found them on sale for 20€ each from Poland, through Skroutz!

Even 20€ I think is too much. As a construction, it's worth it, but it loses its meaning after a certain point. It becomes useless on its own because the kids get bored
