I have one - I love it! I saw one being pushed down the street once before I bought it. I went to the Right Start store on Clyborn to see one and try it out before we ordered it online. (I HATE red and that's all they carried in store. Babycenter.com has them on sale again right now. We waited for their save 15% sale....) I use it mostly as a single, but we attach the double seat in the back when she goes to the babysitters so their daughter can ride too. I don't find it to be hard to push even when both girls are in it. I've never used it in the infant/toddler mode, only single and two toddler. I'm a huge fan. It is pricey, but totally worth it.
