I've only had this car seat for about a month but it has worked perfectly. We previously had the Britax Marathon Car Seat which my son loved. Naturally when it came time to step up to a booster seat, we only looked at one brand. The seat is easy to install (after reading the manual) and provides a snug yet comfortable fit. It is easy to adjust and fits securely in our car (Volvo XC90). The color is fantastic, the cup holders and arm rests are a nice touch as our son loves it.
The lone downside is that it is a fairly large seat and is bulky. You might have to move your front passenger seat forward if you have a smaller car. It is also quite heavy so its not ideal to use if you have to swap it in and out of multiple cars.
You can't go wrong with Britax' quality and safety features. Highly recommend the seat if you're looking for a booster when your child outgrows the car seat.
ProsSafety, ease of use, secure five-point harness, easy to install
ConsBulky, heavy, takes up a lot of room
Best UsesBooster seat, transition from car seat to child booster.
