I have this exact carseat.
It fits nicely in our car and is pretty easy to use. There are two big considerations, however:
1. It's heavy. Really heavy. Even when he was fresh out of the oven, it was a PITA to carry around with my son in it. He's 16 pounds now and we're switching to a convertible car seat because it's frankly just too heavy. And at 27 inches, while he's not at the "maximum" size, he's large enough that getting him in and out while leaving the car seat in the car is like wrangling an alligator.
2. The car seat bases for these are pretty expensive: $45~50 a piece. Other buckets run a little cheaper.
I don't regret buying it; it's worked for us. It attaches into pretty much any Graco stroller like a breeze, which is nice if we're in a hurry. But I think I would have passed on this one and gotten something a bit less bulky.
