Title: Great seat, great features, bulky and heavy
Review: Pros:It’s easier to install than earlier diono radian models ( 3xt,3rxt). The adjustments and strap storage are more intuitive.My daughter loves it and says it comfortable.Cons: it’s very heavyLike all diono seats it’s long when rear facing without the angle adjuster.**In smaller vehicles it can make the the seat in front of it unusable in the infant setting because of the length.It is not as easy to install as our Graco slimfit.

Title: Love Diono carseats!
Review: I am very familiar with Diono carseats as this is my third purchase. My first suggestion is when you get the carseat, to sit down and read the manual. I read a review for this carseat that said their baby was uncomfortable with the headrest down, but the manual specifically says to keep the headrest up for babies. I had no problems installing this carseat rear-facing. In fact, I thought it was easier with the new latch design. It also does not lean as far back as the 3rxt, so in my opinion, the adjuster is optional if in the middle seat. I have a subsaru outback for reference. Obviously, anyone buying this carseat has done their research and knows how hefty it is. IT’S MADE OF METAL. Why would anyone buy this carseat to take on airplanes lol Buy it to stay in your car! It does fold up super easy if you do need to travel and it’s a long velcro strap that keeps it in place. Do snacks get all in the crevices of this carseat? Yes! Does my one year old like to pull the fabric off the headrest? Yes! But he is comfortable and the piece of mind I get from the quality and safety of Diono carseats far outweigh either of those things.

Title: Good buy
Review: I like the quality and durability of this car seat. I’m using it for a toddler and they’re used to a big car seat like the maxi cosi or graco convertible ones so this was an adjustment in the seated positioning. As it is smaller and not as elevated. They fit well and it feels secure and easy to adjust to height.I got it to fit in my sante fe. It’s in the middle of two infant car seats on both sides. The convertible car seat was too big to fit with the infant car seats too. I plan to buy 2 more when my infants outgrow the buckets.

Title: Heavy, Strong, and Dependable
Review: I have a Subaru Crosstrek and this seat is very difficult to install correctly & safely for rear facing. There is VERY minimum space for it to sit rear facing without touching the front seat. It cannot fit in the middle (which I prefer) due to unlevel seat bench. However, this seat is big and heavy. I feel soooooo confident when my 6 month old is sitting in it (when safely installed). Unlike the normal, mainstream car seats, it DOES NOT consist of cheap plastic and a bit of fabric. Even the straps on this beast feel like REAL seat belt material!⭐️ If you have Facebook, please join a Child/Infant Car Seat Safety group. Trust me, you will benefit and so will your child.

Title: Heavy duty
Review: Cup holder is nice. Easy installation. Very heavy. I think you really get what you pay for!! Only problem is for rear facing it very long and I had to move seat up to make it work in my Yukon. But in the mega cab pickup it worked great!!

Title: NOT travel friendly
Review: I thought these seats would be great for travel but they are AWFUL! They are so heavy and difficult to maneuver. The recline of the seat is not adjustable so if you are tall or in a small vehicle either you won’t be able to install the seat correctly or the person in front of the car seat won’t be able to sit comfortably. A total waste of money. Also, the rebound bar burnt my baby’s feet! He had a blister for days.

Title: Fantastic price and quality
Review: Very sturdy and heavy. I feel more confident with my kids in these. We have a 3rd baby on the way and will be getting another one for when it’s out of the infant seat.

Title: Good
Review: Our son and his wife say this is the best brand car seat. It’s narrow enough to put 3 kids in the rear seat in car seats. That’s the report from the users, not mine since we’re too old to have kiddos but sure are enjoying the grandkids 🥰
