We are LOVING this car seat! I really wanted to test all the features this seat had to offer so we tried it out on both our 7 month old (rear facing only) and almost 3 year old (both forward and rear facing position). I received this product at a part of the Stellar Product Testing Panel in return for my honest opinion and review. The easy access belt path makes this seat so easy to install!

This carrier is very good looking, is high quality, and the base makes getting the carseat into the car a breeze! The base has a smart click technology, so all you have to do is set the car seat on the base and it'll click itself into place. Love the stability bar too! caitlinroseirl · britax.com
