We haven't used it much yet, but...
September 7, 2012

I just installed this seat yesterday, so I obviously don't have much experience with it. I just wanted to share my opinion so far. This seat is installed RF, center seat, in a 2009 Maxima. I had to use the seat belt, which wasn't *too* bad, but I'm sure LATCH would be a simple install (as always). The cover is very soft and plush, and I was concerned about it being too warm. That didn't seem to be an issue as we ran errands in mid 90 degree weather. The only issue I was really afraid of was that my little one would try to chew the HUGS pads (I read other reviews that mentioned babies doing this). Sure enough, after 15 minutes in the seat, she went for it. This is where Britax gets 5 stars for customer service. I called to ask a question regarding my install and the customer service rep mentioned the HUGS issue before I could even bring it up. She was extremely helpful and automatically said she'd be sending different pads. Britax sees this is an issue, and seems to be taking care of it. Aside from that, I have absolutely no complaints about this seat. We were able to get a very secure install, my little girl seems to be comfortable, and I feel she is very well protected. We transitioned from the Chicco Keyfit 30 to this seat, so it is a little different to use, but it isn't bad at all. The straps are not hard to loosen, as I'd previously read. Just pull the chest clip, and it's easy.
Pros:
Honestly, everything!
Cons:
I can't say I dislike the new HUGS pads, but we will definitely have to remove them for now. I do think when she's older I will love this feature. The instruction manual is a little overwhelming when you first open it, but the second time I read it, everything "clicked."
