I was crossing an intersection, when the passenger side of my car was hit by an SUV going about 40 mph.

My car spun around a couple times, and I looked back immediately after impact to find that my toddler was fine, and his seat was not moving at all during the spins. I immediately got out and removed him, and while the side of his seat received some marks from the impacting door, he was fine and in place.

The car (a 3 year old Mazda) was totaled due to the extensive passenger side damage.

I am so glad we made the decision to purchase this seat. I LOVE the fact that these tether rear facing.

We replaced it with a Rainier for mine & my husband's car as after a side crash the extra siding seemed nice. However, this is a great seat and I have recommended it to EVERYONE over the past 1.5 years.

My wife and I bought 2 Diono car seats, a Radian RXT and a Radian R120. While I agree with most folks about the quality and such of these Dionos, I find it very, very difficult, if not impossible, to install the seat properly. As we all know, the seat must be secured to the vehicles seat suck that there is less then 1" of movement in any direction. The design of the Diono prevents this. In the forward facing position in harness mode, the location of the belt path is so far rearward (due to the very slim nature of the car seat) that the angle of the belt is almost vertical. Without any horizontal component of the belt angle, there is no rearward force when the belt is tight. Hence, the seat can be pulled forward quite easily. And, the same things happens using the Latch system. Now, I except folks to tell me that if the belt is tight enough, the seat is secure. But all that is happening is the car seat is being sucked into the bottom cushion of the vehicles seat. In a collision, the car seat will flip out of the indent in the seat cushion. Now, if the car seat is reclined and some kind of "spacer" is used between it and the vehicles seat back, some amount of belt angle can be achieved and some amount of security realized. But really, that's what I have to so with the most expensive, supposedly best car seat on the market? And the worst part about doing that is the the whole reason to get ripped off paying such a premium for a car seat is to get an ultra compact seat that will fit in smaller spaces and blah blah. Once the bottom is kicked out forward, a whole bunch of room is lost and the kids legs are jammed up to the seat in front, just like the so-called "big and bulky" car seats. I know, I've had seats from brand X and while they may be more bulky, I never had this issue (in the same vehicle, by the way). To say I'm disappointed is an understatement. Frustrated and ticked off would be more accurate. Because, I don't have enough to do in my life then spend umpteen hours fooling around trying to get a car seat safely installed. Ridiculous. Good luck to you all!

    Comments about Diono RadianRXT Convertible Car Seat:

    My family and I were traveling on vacation, and had an accident after being hit by a semi. Our vehicle did several spins, and rolled several times. My one year old son was seated behind the passenger's seat, the side of impact. As we were rolling his window broke. Once we came to a complete stop, his seat had not moved. He had NO injuries. He was the only one in the car completely unharmed. The car was totalled. I'm convinced it's because of the reinforced steel/aluminum frame. I'm forever grateful for how well made this carseat is. Thank God for the friends who purchased it as a shower gift. This carsest saved my baby's life.

          Comments about Diono RadianRXT Convertible Car Seat:

          After doing a lot of research, the reason we went with this seat over other brands was because it was narrow and would allow it to be next to our infant seat when our next child is born. By far the biggest drawback is installing this seat. We have the seat in the middle and can't use the latch system. Installing with a seatbelt is difficult because you need to use the locking clip and even with it, I still think it's tilted a bit. And we had a certified child seat technician install it! I wish they had a built-in locking clip like our infant seat does. Having said that, I used it in a different car with the latch system and that was a much easier installation.

          My daughter outgrew her infant car seat and this diono car seat is perfect for her. I love that it will grow with her and turns into a booster seat. I also love how narrow it is and fits perfectly into my Nissan Cube.

            I read reviews that the harness was difficult to adjust and I was skeptical...but it is VERY easy to adjust, way easier than the previous seat that we had in our car. Our son (11 months old) seems to be more comfortable and at a better recline position as well. It also seems that he has an easier time seeing out of the windows due to the narrow profile. Overall - we love it!!!

            We have a third one on a way, so we had to find a car seat that is super safe but also narrow enough to fit 3 next to each other in a regular sedan. We don't have this car seat too long, but so far love it.. Feel truly safe with it.

                    I researched many seats to find one that would fit my vehicle, we needed something slim enough to fit 3 across in our F150. It fit great in our truck between two Britax parkways, it was also straight forward to install but we did have plenty of practice with our two oldest before hand!

                    My one and only issue is the pattern we bought, was the flowery one and after 3 1/2 years of daily use it could use a replacement cover. My daughter has never complained about being uncomfortable and we are always on the go!
                    I absolutely love this seat!

                    I got this seat when my son was turning 1, after extensive research. He had already outgrown his infant car seat. He is 2 1/2 now, and 38" tall, but has a long torso. I chose this one because it had the most strap positions, and allowed for the greatest height, both rear and forward facing. For now, he is still rear facing, and regularly falls asleep on car rides. Yes, it is heavy to carry, but with the backpack straps, it is manageable. I was able to carry the seat while pushing my son in a stroller through the airport.
