Update 2: As you read below you will see that I think this is a good seat and recommend it for people concerned about safety. That being said I'm hoping Britax engineers will read this and quit building the CS feature into their seats. As I state below the CS feature of the 70 model is much better than the 65 model, however, it's really just a gimmick. It offers ZERO value to the seat other than letting Britax add another feature on the feature list. The click is almost never enough tension (even if you groom the belt and tighten it around your kids legs first). One should always check the tension of the belts with their hand. I'm willing to bet that parents that rely on the click are not properly tightening the straps. The 70 model is still easy to tighten on your kid, but the CS feature needs to go Britax. The 65 model's CS feature/belt path is well below average in terms of usability. I own two Advocate 65's and one Advocate 70 and would pay 50 dollars right now to remove... Read more

If you're not familiar with Britax, I believe they are the BEST car seats you can spend your money on. We own a Marathon for our very long 3.5 year old and now that our also very long 10 month old had outgrown her infant carrier, I knew what brand to turn to. Since last having a child, Britax has added some new safety features to their already super safe car seats. :)! I won't bore you with the logistics of why this is such a safe car seat, you can watch videos and read the research on Britax's website for yourself (I know I did ENDLESS research as I imagine you're doing right now :)). I can tell you that once out of the box, I couldn't believe how the shell (which is now reinforced with steel bars) curved around and literally surrounded where your child sits. I installed pretty quickly rear facing (with seat belt and tether). If you've done this before, it's not different, lock off and pull tight. If you're unfamiliar with Britax, you can watch a quick video and do it easily. Once... Read more

When I needed to buy a convertible car seat for my older son, I bought a Britax Boulevard. I felt this was the best car seat available at that time. We've had it for a little over two years and it has been a great seat, although we haven't had to test it in an accident, luckily. Compared to all other seats, I always thought the Boulevard was the best quality. However, now that my younger son is large enough to move into a convertible seat, I ordered him the Britax Advocate 70 CS, as this appeared to be the best seat available at this time. Well, it arrived yesterday and I am extremely impressed. The quality is clearly a few notches above the Boulevard. Not only is the fabric superior, but it seems more sturdy and solid. It is wider, though, due to the side impact protection. It seems even safer, too. So, despite the Boulevard being an excellent seat, I just order another Advocate 70 for my older son. I want him to be in the safety seat available, and I am confidant that... Read more
