Well, I bought one and it was delivered yesterday. By the time I got home from work, fed the kids and put it together it was just about dark. I put the kids in it quick and just did a quick walk down the road before the rain came. I do like it. It is perfect for my DD and the twins. DD loved the fact she could sit down or stand up and that she could ride with her brothers (apposed to walk) when she wanted to.
I didn't have time to try to fit it in the back of my SUV yet. I don't have much room back there so it is a concern. I currently have the double baby trend snap and go that fits back there. I bought this because it looked similar in fold up. I should have just bought the Joovy Caboose from the beginning but it was so much money, I was nervous. Plus I was unsure if it would hold both my baby carriers but turns out it does. I had the chicco brand carrier but it will hold just about any. A long list comes with the strolelr. It is so nice that it holds the baby carriers or the babies can sit up in the seat - it gives lots of options.
If there are any soon to be twin moms with a toddler out there, so far I do recommend it.
