Just what we needed, but....
This fit the Chico carseat perfectly once I figured out the angle to get it in. It is quick and easy, pops right in/out of the Duallie. Too bad the sun cover will not go OVER the carseat though. I think that is a flawed design by Bob. If these sun covers were better/bigger and more stable like they are on the single Bob, they would be better and could probably be modified to go over the carseat. Now I have to try to run with a blanket over the baby and worrying about it flying off. Oh well. Still the best (only) option.
I run 20-40 miles per week and easily put over 500 miles running in the single Bob (not to mention all of the long walks we took) and plan to do the same with the Duallie, so this was a must have item.
ProsFits, serves its purpose to safely have a small baby in the Duallie. I have small babies, so they won't fit in there until at LEAST 4 months.
ConsThis thing is expensive for an item that will only be used for 4-6 months. However, it does have good resell value AND AlbeeBaby has it on sale regularly if you just keep checking back!
