We just got ours and opened it tonight. My daughter loves it. It was a birthday present that everyone (all grandparents, uncles, aunts, etc) pitched in to get her. It is adorable and, in my opinion, pretty sturdy. My daughter is 11, so it's definitely geared for her age. She will get a lot of play out it.
It does fit two dolls comfortably and it rolls very smoothly. The lights and sounds are great. It is amazingly cute. I'm glad we have it, even if it's the only thing she gets for her birthday.
