  • Best Car seat Ever
Style: Radian 3RXT SafePlus Color: Gray Slate
This car seat is so sturdy and I feel like my son is so safe in it. He loves it and doesn’t feel squished in it. It takes up very little room and someone can comfortably sit in the middle seat with him. Installation was very easy!

  • What I expect from Diono
Style: Radian 3RXT SafePlus Color: Purple Plum
My daughter is 5 years old & 41 lbs. She needed a new and more comfortable harnessed seat. She requested it be pink or purple. She is forward facing with no seat incline. I no longer hear that her car seat isn't comfy. She's able to cross her legs without them bumping into an armrest. The cup holder is a little difficult to attach but that seems to be the same with all the Diono seats we have owned. This seat is heavy, but once in the car was easy to install. She is over 40 lb so it is installed with the seat belt instead of the latch system. The headrest is a little difficult to adjust but once you get the right angle it moves easily. This is our third Dino Radian for our family. The first two lasted 8 years before I passed them to another family. Would definitely buy this brand again it doesn't disappoint. ... show more

  • LOVE IT
Style: Radian 3RXT SafePlus Color: Blue Sky
Get it! It’s super cute, it’s heavy yes but we get so many compliments on how cute this car seat it and the color is so vibrant. It’s super duty and super safe. My partner and I had researched and looked for car seats since we found out I was pregnant and this car seat was top rated for safety and also for being able to fit 3 in one row! ... show more

  • Do not buy this seat.
Style: Radian 3RXT SafePlus Color: Black Jet
We bought this a few months ahead of our sons birth in September. We specifically went with this brand so that we could fit three cars seats together. We were not able to securely strap this in, in various ways. We were never able to tighten the belt strap all the way and after a few tries the belt strap frayed quite a bit. We were out with our newborn and the release mechanism for the strap got stuck and we couldn’t loosen it at all in order to get our son back in. Luckily we had a back up and my husband had to drive it all the way back out to us. I reached out to the comaony multiple times and all they offered to do was replace the straps. We didn’t want to run the risk of this happening again. So I asked for a refund and they still have yet to respond. I was very optimistic and hopeful for this car seat but it hasn’t been a pleasant experience at all. ... show more

  • Purchased multiple
Style: Radian 3RXT SafePlus Color: Purple Plum
The media could not be loaded. I’ve had 5 of seats. They have all met my expectations. The colors are vibrant and beautiful. The seats fit 3 across, in my Camry & RAV4. The confidence in safety has lead me to purchase multiple times. I’ve had two accidents & my son & grandchildren have been unharmed. These seats are great for the smallest baby to the tallest toddler in my opinion. The kids like them! ... show more

  • Very sturdy, great color
Style: Radian 3RXT SafePlus Color: Blue Sky
I purchased this car seat for my 16 month old grandson. The color is very vibrant and appears to be made with good quality washable fabric. I am happy with the bulkiness of this car seat. It is sturdy and I know my grandson will be protected in it. It has several adjustable levels. I wish I would've purchased this sooner since it is for infants too. This should be a one and done purchase. It can hold children up to 10 years/120 lbs. My son loves it and it has increased his peace of mind while driving with his son in the car. It was well worth the cost. ... show more
