Very Happy
Overall very pleased. Super lightweight and my child is very happy in it. Gives them good sighlines and not overly restricting but still safe.

So lightweight!
We bought this so we don't have to bring our normal car seats traveling. It is soo lightweight we love it! Perfect for bringing on trips so we are not weighed down. And then we use it as a backup carseat for the grandparents if needed!

Being light is the only thing going for it
It’s light, and for that reason works pretty well as a travel car seat (which is what I bought it for). But it is very difficult to install rear facing and is almost impossible to tighten while rear facing. Would not buy.

Great option for travel
We bought this seat for travel and kind of love it. We had no issues installing rear facing with the seatbelt. We can do it fast enough I'm not stressed installing it in an Uber/Lyft/Waymo. There are no bells and whistles, it just sort of does it's job. I wasn't sure our toddler would like it but they are perfectly happy and comfortable in it. I find it very hard to tighten the harness straps once they are sitting in it, so I kind of do it once and then just leave them tightened and clip/unclip as needed. The big benefit is it is super lightweight. We were originally going to travel with a regular seat and we are so glad we don't have to. It's not small though, at least compared to our normal 3 across car seats. Also, our toddler immediately rips off both of the strap cushions that go next to their neck. Chest clip is kind of big, I can't really imagine it working for a smaller baby, but we haven't tried it. I wouldn't really use it as an everyday seat because there are better options out there, but we love this for travel. ... show more

Great and affordable carseat
I am so happy with this car seat! I almost didn’t buy it seeing reviews of the straps being extremely tight and not adjustable but I figured that couldn’t be true. The harness is very much adjustable, both for legs and upper body, please look under the fabric and under the seat to adjust to your child so that they can sit comfortably. The seat is super light to carry and not too complicated to install. ... show more

Great travel option
Light enough that it doesn’t hurt to haul around with the other five million things we travel with for our kid. Not as comfortable as the Cybex Callisto but better than nothing at all. Easy to install in cars and doesn’t require the seat in front of it to be all the way forward. Worth the money.

Light weight has its limits
Does not tighten down or fit well even in an f150. Does not feel very good quality.

Excellent travel car seat
I bought this specifically to travel between Europe and the USA. So far this car seat has been such a great purchase. It's super lightweight, easy to install in a car and plane, and is well padded. I would 100% recommend this as a nice option for a travel car seat.
