This thing is amazing. It is made so well and it's sturdy. As large as it is it's amazing how small it can collapse. The wheels roll nicely.
With what is included, it can be configured in so many different ways. In addition, if you buy more accessories like a second stroller chair, it can be configured in even more ways.
All of it fits in the included bag, though partial disassembly is necessary and the parts need to be placed on the bag in multiple steps. Once on the bag, is moderately heavy and bulky, so you may find it rather difficult to transporting it by hand while in the bag.
The one big issue I had was that the first unit I received was defective. If you look at the photos of the circular piece, that is the joint where the legs collapse, one side was missing a cap, and I believe a steel pin fell out. Something else must have happened, because simply sticking a small screw driver in the pin hole and attempting the collapse the defective leg didn't help. The leg was seized, and even spray lubricant didn't help.
After reaching customer service around the holidays, they sent me a replacement in about two weeks.
The second unit was without defects. While it's a little expensive, if you have two little ones, this will be nice for you.
