Most Helpful Customer Reviews
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...
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...
