I love the idea, but most of the reviews I've read say it is a terrible stroller. The big thing is the weight difference that makes steering awkward and the wheels are all small, also making steering difficult.
I tried it out in the store and loved it, but then came home and read the amazon.com reviews and everyone hated it, said it's mostly plastic and doesn't last long. It really was a genius idea, but I guess something got lost in the manufacturing process, i.e. PLASTIC (sheesh). Can you tell I'm bitter?
