Review: Love It - We just got this delivered today and I love it already. The silver design is pleasant and not gaudy like many other car seat designs. It would honestly work for a boy or girl, although we purchased it for our blue-loving son. The seat itself is surprisingly large and heavy. Its easily as heavy as our youngests convertible car seat. Still, I don't feel like this is a negative. It makes me feel like its pretty sturdy, especially since I know that the heft is due to it being steel reinforced. The included easy latch belt makes it pretty easy to install and gets the seat pretty tight. It even has the belt in the back to secure it further. The fabric isn't soft to the touch but rather smooth and comfortable. The padding is somewhat plush. The belts are incredibly easy to adjust. The push button to loosen the chest straps can be difficult to find but our safety first convertible has a similar set up so it was a natural feeling placement for us. It even reclines! I looked far and wide for a seat that would recline even a little for our three year old since we are constantly commuting to see family and naps in the car are frequent. The britax pioneer is by far the most attractive one I found that was even remotely reasonably priced. With the sale going on, its now priced next to seats with similar functionality like the graco nautilus. Overall, I have been very happy with the seat so far. My son likes it and seems to be comfortable in it. It feels like a safe, reliable seat that is more than just some expensive piece of crappy plastic to prop him up in the seatbelt like the other three booster we went through before getting this one. I'm so impressed I'm considering switching out our younger sons car seat to a britax. Pros Easy to install Steel reinforced Comfortable Big enough to grow with child RECLINES Two cupholders Adjustable headrest and belts Trusted, longstanding brand Con's Heavy May be quite tall for a smaller car
Review: Great quality, great brand, but NOT a Booster - We have always used Britax with our carseats because we trust them with their safety rantings. They are top of the line. This seat is no different. It is comfortable and my daughter loves the armrests and dual cup holder. The seat is easy to install and gives three different options to integrate the car seatbelt to grow with your child. instructions are conveniently printed on the the seat so you can adapt and use it anywhere. The buckles are easy to clip and unclip and are comfortably padded so as to not irritate my daughter while wearing them. It comes with a circle liner to go under the lap clip to not burn kids when the heat has made the buckle too hot. There are just a lot of features like that to make this comfortable and safe for my child. The only issue I have is that I had thought this would detach and become just a booster seat once we were ready for that, but I have not been able to figure out how to detach it yet. It seems the back is welded to the booster so I think it is a harness when your child is using the infant clips and belts and a booster when the child is only using the car belt, but the back does NOT separate from the booster seat itself. Beware and do your research better than I did!

### ⭐ This also seems to be an older model is is nowhere near the quality standards as the clicktight version that we have and love. I
*by J***S on January 5, 2015*

My car does not have the latch system and we were never able to get this seat installed and returned it immediately. The seat belt does not lay correctly through the seat and it is not designed to accommodate the correct angle of a seat belt. This also seems to be an older model is is nowhere near the quality standards as the clicktight version that we have and love. It seems very cheap in comparison and has sharp edges that I cut my hand on. There is no room to use a seat belt tensioner so there is no way to install this tightly on a belt-only car. It might work fine with the latch system, but I felt ripped off anyway with how much I paid when it came to the quality of the product.
