    Safest Car Seat for our Little Ones!

    Customer review by An anonymous customer

    5.0 stars by An anonymous customer

    We started off with a Britax. Britax makes an excellent car seat, however, with our numerous travels and additions to our family, we had to change. The Radian RXT was the ultimate choice for 3 reasons. 1. Unparalleled safety ratings and construction (including ease of cleaning vs. Britax); 2. Lower profile. Other car seats put a higher percent of our babies' bodies exposed to the window/glass area. We opted for the lower profile to put more steel and mass between our children and the source of any collision; 3. We expect to be adding a 3rd child to our family and the Radian RXT is the ONLY car seat that you can fit all three, side-by-side. We take these car seats with us on every flight, in every car/van rental and wanted to make sure that no matter what seating arrangement we ended up with, all would be able to fit together. There are a few disadvantages to these remarkable seats. One, they are heavy and tend to lean towards being more of a fixed car seat rather than a portable or easy travel car seat; Two, the car seat has two recline settings, none which recline our children comfortably when forward facing. Rear facing is quite the opposite, the recline is so severe that it prevents our drivers seat to be comfortably set without hitting the car seat (Impossible in our Range Rover and just enough for our Honda Odyssey); Thirdly. Cost. These seats are expensive. We are relying on the safety ratings and excellent construction to warrant the cost. We have never been put in a position to test them (hope never to), but I have seen pictures and read stories on those who have. If I had to think of another seat that I would rather have, it would be one made of steal and have an enclosed roll cage j/k. NEVER BUY A USED CAR SEAT UNLESS IT IS FROM SOMEONE CLOSE TO YOU WHO NEVER HAD IT IN A WRECK. ( I must clarify. Someone close to you, who is responsible, honest AND never had it in a wreck).

    I travel A LOT and this carseat allows me the flexibility to bring it anywhere. I have to fly a lot and I really love the ability to strap it on my back like a backpack through security. It makes traveling through airports much easier. My daugther loves it which is another bonus, it feels really comfortable as well. I also have a convertable Britax which I refer to as the throne. I love that carseat too, it just isn't as practical to take it through the airport. I have told my friends to go out and buy it especially if they travel a lot like me. It's frame is strong and solid as well. I hope this helps! It is worth the $$$

    Best Seat I've Used!

    Customer review by SWINEGA

    5.0 stars by SWINEGA

    We have owned several infant, convertible, and harness booster car seats. This is hands down the best one of them all. Yes, it is a heavy seat, but the seat is high quality, long lasting, and narrow. We chose this because it is narrow and we have two kids in the back of our cars. We wanted to be able to allow a third person in the back seat. In one car we have this seat RF and use the angle adjuster for our 2 year old, and we have a harmony defender for my 4.5 year old (also as narrow as the radian, but it's a harness booster, so not for little little ones. Easily we can fit a third person/car seat back there. In our other car (of similar size) we have 2 Safety 1st Complete Air car seats. One RF one FF, on either side of the back seat. They TOUCH in the middle. There would be no possible way to fit a third seat or person back there. This seat is high quality. It's very easy to install. They shoulder pads are large, but make it very comfortable for my daughter. They take a bit to get used to as far as buckling the chest clip. If you really don't like them, you can cal Diono and ask for the smaller ones, they will send them to you. Also, this seat is different with tightening the harness. The mechanism is more of a ratchet type, where it's more like tug tug tug, rather than just pull til it's tight. Another thing you need to learn/get used to. As long as you read your manual and familiarize yourself with the seat, you'll be great! Even with the angle adjuster in, my 2 year old sleeps comfortably and her head does not fall forward. Please do your research on seats before buying. Never buy a used seat. Never use an expired seat or seat that has been in an accident. And lastly, keep those babies rear facing as long as they fit according to your seats specifications. It is MUCH safer.
