I bought this 2 years ago and recently discovered that the side head impact cushion had come apart from the actual seat. I called and they sent me a brand new car seat in 2 days! So happy I went with this car seat as i really feel like my daughter is very safe in it. Thanks for replacing it!

We bought this car seat to install it rear facing in my Mazda 2 (super small car) and it fits perfectly! It seems like we will be able to rear face our baby for as long as we want to. Very easy to install and doesn't take up a lot of space.

I bought this because my niece was in a Britax convertible years ago and my older daughter has 2 Britax forward facing seats. I LOVE the Britax Frontier with Click Tight, so I knew I'd want to get a convertible car seat with ClickTight for my baby. BUT this seat is SOO heavy it's hard to move (which I try not to have to do but it's the only seat we own since it was so expensive). The ClickTight is not easy like with the Frontier it is extremely difficult I can barely get it closed I have to litterally put my knee on it and press with my body weight and wiggle to make it click (and most times it takes a few tries of doing this). Getting a car seat properly installed can be difficult and exhausting and I thought the Marathon with ClickTight would help me not have so much trouble but that is NOT the case it is just as difficult (in some ways even more difficult) than other seats. It does have a no rethread harness but the straps on mine get uneven when you loosen and tighten them and you have to take the seat out and loosen them all the way and tighten them all the way a few times to make them get back to even and then REINSTALL the seat (which is a huge pain) and defeats the purpose of the no rethread harness for me because it's much harder to do that than to rethread a car seat harness. and lastly there are no cup holders which is not a big deal but had I known it was going to be so difficult to use I would NOT have bought it and would have opted instead for a seat with more features (such as cup holders)

I'm a LONG time Britax car seat and specifically a Marathon user. I'm looking to purchase our 6th Britax convertible car seat for our youngest baby girl, and I'm soooo disappointed in the color options for all of the Britax convertible car seats. I've never had a problem finding a "girly" color option for my girls, but that no longer exists. This seems like a MASSIVE oversight/poor decision. I don't know any little girls who wouldn't pick something like pink or purple over gray and black. I've loved all of our Britax car seats, but because of something as silly as color, I'm planning to switch brands.

I bought one last year 2017! Easy install, great material, and just amazing! We had to get a replacement and they sent that out within two days! Great customer service as well

I bought this for my 4 mo daughter for Christmas. She was previously using the B-Agile Infant car seat and seemed uncomfortable. This car seat is awesome, seems super comfy for her. Riding in style!

Very happy with it - cozy and snuggly and comfy and protective
