I have the Mosaic - I like it (as much as a babywearer can like a stroller!)
We don't use a stroller very often, but I wanted one that was light weight, folded up small, and wasn't HUGE. It fits the bill, I can do everything one handed with it. Including lifting it up out of the trunk of my car, set up and tear down.
Quality is just so so, we've had a buckle break and the wheels are plastic.
Over all though, not a bad little stroller!
