Zuzu Pets

Zu Zu Pets the newly buzzed about toy are battery operated hamsters that move around like a life-like animal in their play sets. Is that true? Are they good?? I have a few nephews and cousins visiting and I’m planning to gift them a lot of them and need to do a thorough research. Someone please tell me any and everything about it. Is it possible to pre-order at some site. I want to get the best deal available. What about the discounts they offer??
