10/10 we love this brand and the car seat
Britax is just amazing. Our little one first car seat was britax as well and she grew out so we needed a new one and we tried other brand that didn’t meet our expectations so we decided that definitely this brand would work for us. The installation it’s easy. It’s very soft and comfortable for my daughter, doesn’t move and feels safe. It isn’t the cheapest but definitely worth the price. Hope if we have another baby britax send us car seat for free 😂 we love you guys 💕

Love these car seats
Both of my kids are in the Britax One4Life car seat. I love these seats and how solid and nice they are. They are comfortable for my kids and easy to put in and take out of the car. They are a bit heavy but that doesn't bother me because of the quality and feeling of security that my kids are safe. We have the gray and black color ones and are happy with them and how nice they look. I would buy these seats over and over again.

Car seat
Might have good reviews but I can't pick it up. Very heavy and wide

Great car seat
3 kids later and this is now our 3rd one we have purchased. Very easy to install and uninstall. Easy to clean. Easy to get kids in and out and set up safe for drives. We'll built and comfortable. Our oldest one is 4 years old and we have had no issues. We have a spare graco car seat we just tried getting bye with for our newest child and it is no where near as nice or easy to use. Had to just purchase another one of these!
