Great seat
March 22, 2017
Yes, it's a little heavy but it makes me feel like it's actually as sturdy as it claims. The buckles are pretty easy to work and the straps come with shoulder pads so I don't have to worry about them digging into baby's neck. Wouldn't be one I'd want to change back and forth between cars regularly but as a single vehicle seat both baby and I like it.
ProsSafe Fun color Padded straps
ConsHeavy Couldn't fit rear facing in a sedan

We love this car seat. We had one and bought a second. It's easy to install and the straps never twist. Both our kids like it and seem comfortable.

We love this car seat so much that we ordered a second for our other vehicle. The price is definitely worth it for piece of mind.
ProsFits 3 across in most vehicles. My two teenagers have plenty of room in the back seat with the car seat. My 2 year old is very comfortable.
Best UsesAny age.

Hands down best car seat I have ever owned!!
March 1, 2017
This is the best car seat I have ever owned. Still have one I bought 6 years ago and it's as good as it was brand new. I have 5 kids in car seats and everyone of them Ride in a Diono RXT or Diono Radian.
ProsSize, durability, safety, ease of install, high weight limits.
ConsPrice (defiantly worth the money just hurts the pocket), heavy (also not really a con as that's what makes me feel it is safe).

High Quality Seat/Highly Recommend
December 22, 2016
I chose this seat for these reasons: (1) replace car seats after an accident; (2) the size so that we could purchase a sedan over another gas hogging SUV with baby #3 on the way. I could not be more impressed with the following: (1) how fast Albee Ships; (2) the design of the seat is like no other, it is rock solid, the instructions are clear, and the installation videos on Diono's website were incredible. Please note this seat is definitely not for someone who does not want to take a lot of time to set up and install. I read the new car manual and the installation manual (more than once). This made my first attempt at install work seamlessly.
ProsQuality, design, safety features, size
ConsInstallation takes some self education so that you make sure you get it right.
