5.0 out of 5 stars Wish I would have bought sooner
By Kayla on September 22, 2020
So I had to order 3 of these carseats and it for sure was not taken lightly as these are pricey. BUT in the end we absolutely love them. They fit perfectly in Chrysler pacifica 3rd row. First the good
--super easy to clean
--very narrow(the only issue is they are very long so if you are rear facing as you can see in the photo it sticks out alot)
--Buckles are SO easy

Cons
--i have 3 kids and have installed many a carseat. When I say these are by far the hardest I mean it. Im not sure if it was because we have so many or so close together but whatever the case this is not a carseat you Uninstall all willy nilly.
I am very happy with this carseat and if you have 3 under 2 like me, just buy it and save yourself the time of trying to make 10 other carseats fit 3 across.

After one wash the whole back of the cover is ripped! How is this product supposed to stand the test of time? Waiting to hear back if they will replace it.

1.0 out of 5 stars Misleading information
Reviewed in Canada on February 7, 2021
Got the chair because it says it is steel core made; even the image where this is mentioned shows a grey (like steel) core but it is not true, all is plastic just like any other chairs. The chair design in fact is not bad at all, the material that covers the core of the chair is good, but this chair is being promoted with misleading information.

Reviewed in Canada on October 26, 2020
I loved mostly everything about this ! First of all, they seem to have sent me a 3RX instead, which is a step up, so I’m not complaining! The fit is incredible! I found it easy to get a good install, & it fits so nice and snug leaving so much more room in my car. My son has only been in it once so far, but says he loves it! The only downside is I find getting the harness to buckle tightly is a little tricky with the harness covers, but I bet I’ll get use to it!

They have changed the buckles on the car seat, they use to be so nice but now feel and look cheap. The blue cloths pic is the new ones and the pink is nice ones. Too bad was my favorite car seats before.
