Definitely recommend!
We purchased this car seat for our daughter and it was well worth it! She fits in it perfectly and it is super easy to install and clip her into. Have already recommended to friends who have bought!

Diono RXT
Super easy to install the seat with the latch. Haven't done a seatbelt install yet so I cannot speak to that. It reclines much farther than our Peg Perego convertible seat which is great for young ones. My daughter is over two, very tall and light and I plan to rear face as long as I can. This seat is excellent for that. Fits well in a larger sub behind the driver (we are 5'9 and 6'0). I still bough the angle adjuster so my daughter is sitting more upright. I definitely recommend the adjuster if you have a car or mid size or smaller suv.

Love the seat. Super easy to use. Padded chest straps. Comes with a cup holder. Ratchet style harness tightening. Very happy with my purchase.

Sound purchase
You get what you pay for! Great seat, easy to install, stylish, sturdy and safe! My only pitfalls are price (I wish we had four...we eventually may!) and the straps sometimes do a lopsided tightening but that seems to be the nature of most car seats. We are always able to fix it up before driving everytime. We have taken our Dionos on planes as well with no problems and easy lugging. Love the carry straps, angle adjuster and car seat cover also.

Happy with purchase
Love the quality of this car seat! Easy to install and very durable. Also very easy to put baby in and adjust the harness. Would buy another for baby on the way! 2 would fit very well in a compact SUV.

Great seat, worth the $!
Love this car seat! Narrow, and easy to install. Our daughter seems very comfortable, and it has great safety ratings. I really liked the fact that it was able to be rear facing for longer than most other car seats, which is safest for baby!

Comfort for baby
My baby hated his infant car seat and would cry non-stop during travels, but as soon as we transitioned him to his Radian RXT, he was never cranky and sleeps during travel. He's comfortable in it. I'd buy this again if we'll have another baby.
