Katelyn McCune: Just had my 3rd baby, and did not feel like buying a bigger car since my Honda civic is almost paid off. Decided to see if I could find a carseat that could fit 3 across in my tiny car. Thankfully I came across this! Had to buy 6... 3 for my car and 3 for my husbands. Sucked forking out that much money but it was honestly worth it! Great quality carseats and I definitely feel like my kids are safe in them. Only downside is if your car is a little smaller, you might have to move yours seats up some if you are rear facing

Lily: By far this is the best car seat I have ever purchased. I have a Subaru ascent and I have six children which only two of them are in car seats and the other two are on booster seats. They fit perfectly, the way I put them in my car I put one of each side and one of the older child sits in the between them and he has plenty of space,the material is made out of is fantastic and it's not hard like most car seats it's soft and it's made of some sort of phone material so the child is extremely comfortable. Neither did my 8-month-old nor my 3-year-old complain when we took a 2-hour drive so I highly recommend these car seats. I personally think it's worth the money.

Gabe: I was wary about this seat because I’ve heard so many folks complain about difficulty installing it. While I didn’t try to do so rear facing, the forward facing install was a snap. This thing has a tiny footprint and really high quality materials. Next to the larger car seats, this one looks like a sleek little race car harness setup! I really appreciated all the attention to detail, like the super comfy and plush chest/shoulder pads and the ingenious LATCH clips (haven’t seen those anywhere else!). I really like this seat and frankly wish I’d gone with this for my other children as well — would have made for a much easier 3 across setup.

Tarar: The directions were confusing and the pictures in the directions referred to parts that were not included in our product, like a large sleeve for the directions that apparently used to exist on the back of the car seat . We also had a large red strap that was not identified in the picture that was confusing at first as to what we were supposed to do with it. Later in the directions, it referred to the red carrying strap, which clearly is what this is, but not showing it in the diagram led to confusion. We have 4 kids and have been through many car seats, so I don’t think the issue is us, but that the directions weren’t updated completely for revisions to the previous model. At first, when the directions didn’t seem to match the product, I wondered if what we received was authentic, but I’m 97% sure it is at this point.

The seat itself seems sturdy enough and is slim compared to many models, which is nice. Our little guy is 2, but on the smaller side. I try to picture him sitting rear facing at 50 pounds instead of 28 in this seat, and it doesn’t appear there will be tons of leg room, but right now, he fits great. I’m also not confident the cup holder will stay...

Al. Mo.: Great improvement over last year's model, folds up quite easily which is a plus
