Rated 3 out of 5 by from Wonderful but VERY hard to tighten We are die hard Britax customers. The Pioneer is wonderful for my son who is very tall. It will fit him for many year. My only complaint is that it is extremely difficult to fully tighten the straps. We have uninstalled and reinstalled the seat numerous times with the same issue. I have to stand on our bumper and pull with all my strength and still it seems to stay somewhat loose. In addition, the seat fabric ripped 1 week after we installed the seat at the seams. I would probably not use this seat with my other children.

Rated 2 out of 5 by from Would not recommend I bought this car seat for my three year old four months ago. I researched and decided to go with this one over the diono I normally buy. Huge mistake! I despise this car seat. There have been many days that I wanted to sit this car seat out by the trash. It feels cheap, it does not tighten easily, and it a very awkward seat in the back of my van. My three year old often complains of how uncomfortable it is too. I would definitely not recommend this seat

Rated 1 out of 5 by from Very hard to tighten! I am upset with the performance of this car seat. We had a Britax convertible car seat first and LOVED it (still do for my younger child) but this car seat is so hard to tighten that I get upset/frustrated every single time I have to put my daughter in it. I plan to buy another seat instead.

Rated 4 out of 5 by from LOVE this carseat We purchased the carseat about a month ago, I am so glad I did. This was my first Britax purchase and I am so happy we went with this. We had another brand that was highly rated and everyday I just wasn't comfortable with my five year old being in it. This seat is a world of difference the weight alone made me feel more secure with it. I found it to be easy to install and had no issues at all. My son loved the straps and the seat overall. I plan to by another in a few months for my other son when he is old enough for it. I will only be buying Britax from now on. The quality is far superior than others.
