In theory, the Chicco S3 All-Terrain stroller seems like an excellent product. It's extremely maneuverable thanks to its three-wheeled design, has a lot of storage and convenience features like cupholders and storage options and converts to a travel system (but only with the Chicco KeyFit car seat) for a full-age-range stroller. Its adjustable handle and large, padded seat, meanwhile, appear to offer a high level of comfort for adults and children. Yet it doesn't seem to have caught on, though it was released in 2009. Perhaps that's because of the price. If that is a concern, the Jeep Liberty Limited 3 Wheel All Terrain Stroller is loaded with features, accepts a variety of infant car seats and gets excellent reviews overall.
There are no expert reviews of the Chicco S3 All-Terrain Stroller, but we did find a few owner reviews at Amazon.com and Buzzillions.com.
The couple reviews on Amazon are both favorable. One New York City reviewer likes the S3's carrying capacity, while another has taken full advantage of the travel system option. They give the stroller 5 out of 5 stars.

The Chicco S3 Cortina Together earns 4.6 stars (out of a possible 5) in a handful of reviews, with owners saying it's durable, highly maneuverable and easy to stow. There do seem to be a couple of issues with directions for assembling the stroller; some say they are difficult to understand.
