Are you talking about the Zeus Turn or the Zeus 360?
I would never, under any circumstances, recommend the Zeus Turn. It only has a 22-lb rear-facing weight limit, and many kids will outgrow that before they can legally (and WELL before they should realistically) be forward-facing.
It was also very confusing to use and install.
Combi has made a lot of changes with the new Zeus 360, though. It has a higher rear-facing weight limit at 33 lbs. (Though that is still among the lowest out there), and they have supposedly changed the design so it's easier to install.
One of the writers at carseatblog has one (and I believe is preparing a review), but other than that, it's still very new and I don't think many people have seen it. (Come to think of it, I think there's a very brief video of it over at carseatblog.com.)
Even with the improvements, though, I see this as very much a niche seat. I would possibly recommend it for someone with disabilities that cause difficulty loading a kid into the car, or maybe for two-door cars since it can be hard to get rear-facing kids in there.
Do you have a specific reason for wanting that seat?
