I got a Blvd CT today and so far it's going back.
I had a Marathon G4.1 before and liked it well enough, hate how high it is but no biggie. The Blvd CT was a pain to get set up correctly, though might not have been if I hadn't also been focusing on my husband and two littles at the same time. My biggest complaint? The harness is SHORT. Super short. Much shorter than the Marathon one. And yes, I already adjusted it from little baby mode into older kid mode. My 2 year old is 30lbs or a bit under, 37" tall, I don't see how this seat will possibly get him anywhere near 65lbs. And the button to loosen the harness is SO buried. I'm sure they were trying to prevent kids from loosening. Well, good job, I can't loosen it either, lol. My fingers aren't hardly long enough and it hurts my wrists to bend that way. So I'm almost positive it's getting returned which stinks. So it's either buy another Marathon like I had before or I may replace it with one of the Graco seats. DS really likes having a cupholder, lol. I like the NextFit, too, but alas, no cupholder and really no reason in my mind to spend that much if it doesn't have some sort of anti-rebounc protection, a cupholder, or some other outstanding feature.
So there's my opinion for what it's worth. I kind of hate it. The installation, clicktight part? That's fabulous. Everything else, not so much. They've lost that butter smooth harness adjuster. And I HATE the new HUGS, too. And they should build the cupholder into the seat so it's not sticking so far out the side of an already really wide seat. THere. I think rant over. I like the Extend2fit.
