We purchased the Zooper double stroller when my son age 1 & son age 3 months. I knew I needed a double stroller for both boys that would hold the car seat on one side and a toddler on the other. The stroller is very smooth while walking around the neighborhood but does not work well at the mall. It is very bulkie and hard to get into some stores. It has allot of space for the boys to sit in and they seem to like it very much.  The large basket underneath has a support bar arcoss so you really can not use it for much. I like the stroller for the most part but if you go shopping, leave it at home....
