hi, just wondered if anyone had any experience of this pushchair? I bought one on a bit of a whim-wanted something lighter and smaller than my pram that actually comfortably fitted in the car boot and this seemed to fit the bill and was cheaper than a maclaren xlr! I've never seen anyone with the Callisto, so hope it's going to be okay! So far it seems well built and does everything I need but just wondered of anyone had used one and what you thought?! Thanks!
