I am buying this carseat after owning a britax advocate 70. My 4 mo old was in the seat when we were in a car accident. He was safe and sound! This seat is big but if your car will accommodate it, I think this is the safest seat out there. We had ours in a '99 Honda Civic and now in a 1210 Honda Crv. I had both seats professionally inspected regarding installation. It's big but its worth it!
ProsSafety, price, durability
ConsNot the smallest seat on the market, probably won't fit all cars
Best Uses'99 Honda Civic, middle backseat, rear facing
'10 Honda CRV middle backseat, rear facing
