I did a lot of research on my third child's car seat. I needed a high rating (as always) but also compact for my compact car that would have 3 kids I. The backseat. This car seat is AMAZING. The base is easy to install, the handle glides into place, there is so much comfort in the seat, and it fits in backseat with plenty of room for everyone else. I dread having to get s new seat to replace this one when she is too big for it. The stroller is also awesome! It guides well and is fine on grass, gravel, and other terrain. I can't say enough good things about this system. By far th best set I've ever seen.
