We have a mostly love and a little bit of hate relationship with our Dionos. We're not the most patient people, but we've finally put a little muscle into these seats and we've come to love them. If you can stick with these seats, I think you'll find, like we do, that they're a great investment. But, I'll also tell you why they will make you cry at times. If you can bear with this lengthy review, I will let you in on the secrets of the awe-inspiring and tear-inducing Radian.

Why we love these seats (we own two, one for each car):

(1) The Radian is a tank. To my knowledge, it is one of only two seats on the market that is fully steel-framed. The Clek Foonf is the other one, which is unpronounceable, more expensive, and doesn't last as long: your child has to be able to sit upright before using it and it only lasts until the child is 65 pounds. At the rate my child eats, he will be 65 pounds by a year-and-a-half, which would be not long after he started sitting up. Now, with the Radian, although all car seats have to meet government safety standards (quite easy to forget in the guilt/hype advertising of buying baby products), we feel a great sense of peace and security when going on long car trips with it.
(2) The Radian is narrow and therefore still lets you have some of your backseat. When my wife and I were young and naïve (approximately 1 1/2 years ago, while expecting our aforementioned first child), we thought we would have three children, or we at least didn't want to have to re-buy car seats because of that possibility. So, we initially gravitated toward the Radian because it's a super narrow seat and allegedly fits three across the backseat of cars.

I was just in a major fwy car accident. Hit at 60mph and spun through three lanes of traffic with my kids (ages 1,2,&3) three across in this car seat. The kids did not move an inch and the car seats withheld the impact to a degree I never thought possible. My kids came out with no injuries aside from a tiny (1 inch) skin irritation from the strap on my only forward facing child on the side of impact.

I would like to start off by saying thank you to the people at Diono for making such a amazingly safe car seat. My wife and 18 month old little boy were in a terrible car accident a few days ago due to the negligence of another driver failing to yield on a left turn at a red light. The speed limit on Goodman Rd. is 65mph and my wife says she was past the line in the intersection when the women decide that she still had enough time to make the turn in front of them. My son was buckled/strapped in forward facing in the middle of the back seat of my wife's Lexus es300 in his Radian RXT when the two cars collided. My wife says she was going approximately 55-60mph when she hit the brakes but it didn't do much seening as that there was no time stop. This car seat did its job to PERFECTION and my son made it thru the accident with only a little rub on his neck from the harness belts! We took my son to his primary care physician that day to be examined and the Dr. Said he was in perfect shape and for us to turn our worry buttons off. This car seat is worth every penny after all our little ones are priceless and I was just reminded of that the other day and everyone always thinks an accident like this one will never happen to them. This accident took place no more than 5 miles from our home. This was one of the scariest moments of my life and the good lord definitely took care of my family that morning. My wife car is the Black Lexus and the person who turned in front of her was driving the Blue Honda. I will be writing Diono a letter soon thanking them for keeping my son alive and not only that he walked with only a tiny scratch because of the seat. BTW the other lady didn't walk way. She is alive but severely injured so next time your out driving be safe and think before you act.

I bought this seat for my tall (38in) and thin (28lb) 2 year old daughter. I was impressed with the height the seat allowed for, given that my child will out grow a seat in height long before weight. I needed a seat that would fit in a 2012 Focus and was FAA cerified. The seat is very compact. It was easy to install using the seat belt and the latch. Since the seat is so compact I had enough room to get in the car and put my knee in the seat to help get a solid install. I was able to do this myself in just a few minutes, even in an airport parking lot.

My kiddo loved the purple color. That particular color is a micro suede type fabric that is super easy to clean. The wings support her head well when she is sleeping. She can climb in and out of the seat very easily since it is much shorter in rise than her old seat (an Evenflo Symphony). The clips are all great quality and the shoulder pads are nice and soft. She feels less boxed in sitting in this seat. She loves that she can reach things if she drops them next to her seat.

I used this seat for air travel shortly after purchase. I found it fairly simple to deal with. I am a 5'5" woman with a broader frame. I travelled by myself with two kiddos, 2 and 8 years. We did not check anything, we carried all our luggage on. So that fact that this seat can be carried like a backpack was very helpful.

Some tips for air travel with this seat:
Get two (2) carry straps for the seat so you can wear it as a backpack. This makes the weight easier to bare, is better for your back and keeps your hands free.
Have rubber bands handy to roll up extra strap length. The latch straps are very long and can get in the way when trying to install on the plane.
