Own two!
I liked this for my third child so I ended up buying another for my fourth and will use one for the one I am expecting after he or she outgrows the infant seat- although this seat can be used form 5 lbs if that is the preference. It has higher weight and height limits than many similar seats allowing children to rear-face and use a 5pt harness longer for optimal safety. It is also easy to adjust the straps as it is in the front of the seat below the child's legs.

Awesome car seat!
LOVE our Diono RXTs, we have two. Our 7 and 8 year olds are both still in 5pt harness mode (they're light weigh rugrats at 50 and 54lbs and 48"/50" tall) they've had them for 4-5 years now. Roomy, comfortable and easy to clean. Only con is its a bit hard to tighten the harness line after years of use.

These seats are great!!!!
We have 3 Grandchildren of different ages and all 3 seats fit in the back seat of my Toyota Corolla. My husband could set these up for each one's weight. I love that these can be used for years to come. I had priced them elsewhere and was pleasantly surprised at the prices at Albee Baby. We are very happy with our purchase and the the delivery time.

Best car seat for my 3 year old!
I was a little skeptical about this car seat when I first saw it but after reading reviews, I went for it and let me tell you, its so worth the money! We have a small car (Ford Fusion) so I wanted a good car seat for my three year old that would keep him save. Before this one, we had a Britax Marathon, I loved that car seat, but when I received this one, I instantly fell in love with it!. However, it is heavy, but I don't mind that at all because we do not take it out of the car. I highly recommend this car seat if you have a small car like me!

Loved BUT hate.
Love this seat and we were hoping that it would be our last seat ever to purchase seeing how it has a 12 year life span. However my 38 lbs daughter at age 7 is 50'' and can no longer ride in the 5 point harness safely and will not adjust any higher. when switching to booster mode the seat belt will not retract correctly the headrest and the side of the seat is to tight of a fit for it to retract if she leaned forward for something. But she dose love this seat its comfortable and fits nicely in the 3 row when we need to put all 3 of them together.

Very nice and comfortable
We upgraded to this car seat for our 10 month old after long research. We felt confident going with Diono as reviews and test has proved this to be the safest car seat in the market. My daughter is extremely comfortable in this car seat and I really wish we could've gotten this from infant stage. It is very slim and nice looking. I gave it 4 stars because it is extremely heavy, but other than that I love it and recommend it to everyone.

I would not buy this car seat, or recomend it to others!
I purchased two (2) of the Radian RXT's approximately 3 years ago when both my children were still in the 5 point harness. I chose this model because it is advertised to last you through until booster seat age. This car seat was EXCELLENT when used as a car seat with the five point harness and well suited to babies and children 12 months to 4 years old. Once I removed the 5 point harness and converted (BOTH) my car seats to booster seats, I encountered the following problems: 1) the headrest does NOT extend high enough for a 6 year old (40 pounds) to fit in. 2) once the head rests on BOTH the booster seats were adjusted to the right height, they fall down and I have to fix them every single time I buckle my kids into their boosters. 3) My kinds complain that they are uncomfortable all the time, due to the head rest dropping bellow their shoulders. They are an absolute nightmare, and very unsafe once the headrest falls during long drives and it ends up behind my kids shoulders. I did call customer service, however they suggested tightening the bolts behind the head rests, this did not work. They still fall. I am now looking to replace them urgently.

Much better car seat!
We had a different model before and found that after using these life got a tiny bit easier. Installation was pretty straight forward and buckling is much easier! The best part is that we can fit three next to each other so it saves us having to commit to buying a new car!

Excellent Car Seat
We have used Diono car seats for over a year now and we love them. Especially great if you travel a lot and need to bring a car seat on the flight. Easy to travel with. We decided to upgrade our Diono to the Radian RXT. Very happy with is so far. We like having the headrest for our now 2 yo son. Previously we had the Diono Radian 100 and we love that one too.

Improved Diono Radian RXT
Love this car seat! We love how slim this car seat is. It allows you have 3 car seats or a mixture of 3 car seats/people in a row. It's very easy to put you child in and tighten straps. I like that they added a thin pad around the pelvic area buckle. It makes it more comfortable when child is in shorts or a dress so the buckle strap does not dig into the skin. This is an upgrade within the last year.

Great recommendation.
I got this at the recommendation of a friend with 5 kids and a friend with 3 kids. I am on my second kid with plans of 4 so fitting many seats in a car is important. So far we are just rear facing. It was easy to install, takes less room then our previous seat. Our daughter rides comfortably in it. We are currently awaiting the arrival of our second seat. I will also note, I'm a doctor and extended rear facing is important. This allows us to do it.

Excellent purchase!
I just recieved two of these for my 2013 Nissan Murano. Previously had two Britax Marathons. One is rear facing, the other forward facing. We love the extra room they provide in the back seat wirh them being so narrow and the cup holders. Also love that our kiddos can see eachother face to face in them! First use and they both knocked out comfortably! We love them!

Love it and people should read there manual
This car seat is amazing , its strong and wonderful. Half of the reviews on this site is people who can't read a manual , you can use more then a seat belt for forward facing , it comes with straps with a awesome easy push button straps to hook to the bars. If the car seat is to big rear facing because you can't back your seat up. Put your seat in the middle wear it should be anyways. Read your manuals people . This is amazing , I have a 4 year old daughter, and she's been using it sense she was 6 months old. And we will be using it till she beats the highth or weight limit!

Perfect Fit
We purchased this carseat in order to fit three carseats across the backseat of our van. This is the only carseat that would allow for this that would fit the size and ages of the three children who would be using them. Albee Baby offered a %20 off promo which saved us $60.00!! This was the best price on top of free shipping that we could find after months of shopping around. The seat itself is amazing and holds true to all the reviews and the product discriptions.
ProsVery narrow and the seat folds flat when not needed for easy storage
Consit is very heavy... but that adds to its safety for child so worth it!
Best UsesThis is truly the only carseat you will ever need for your child from 5-120lbs!

So far so great!
I've only had the car seat for about a month now but I think it's great. Easy installation, very roomy for my tall 18 month old, pretty heavy but worth it. Compared to other seats it's a excellent price because it converts to a booster.

3 Across the Back
This is the third Diono we have bought. We just switched our third from his pumpkin seat to this and it fits very well rear facing (with the adjuster- sold separately). When front facing, this seat is prefect, when backward facing, it is very hard to tighten the shoulder straps. I can't figure out why but the strap is nearly impossible to pull no matter what angle you attempt. This is not the only seat with this problem, though. Almost all of the ones I have used have the same problem.
ProsSuper solid feel. I'm confident it is a dosage seat. Narrow to fit three in the back seat. This is the only see I can do this with.
ConsVery hard to tighten the shoulder straps when backward facing.
Best UsesInfant who can sit up on his/her own and older.

I wish I would have purchased this first!
I recently purchased two of these seats because we are having our third child and there was no way we could fit another seat in our car. The box was smaller than any car seat box I've ever seen (as it comes folded), and I was pleased to see how narrow it was. I hesitated at buying these seats when my other two were due for new seats, but instead purchased two different Britax seats--great seats but definitely too wide to fit a third. I would suggest if you plan on having three kids or more save the trouble and buy this seat up front.
ProsNarrow Folds flat for travel
ConsHeavy Not compatible with inflatable seatbelt position--I wish I would have seen this before purchasing, but we shuffled seating arrangements (but not all passengers are happy with current placement)
Best UsesThree car seats in a bench row; low height makes it easy for children to climb in and out

If you bought this thinking you'd never need another seat...
DO NOT buy this seat if you think it's the only seat you'll ever need or if you want it for a FF older child or a booster. They outgrow the straps so quickly and it is highly unlikely the child will be able to use it to 54" as advertised and will probably NEVER use it as a booster. Look closely at the children in the ads, they don't look that old and their shoulders are right at the top of the strap allowance. The seat is useless if the straps come out below the shoulders when FF.

I have 4 of these and will be buying my 5th
I have tried over the years many different car seats some which after a few months plastic snapped or car seats broke. As We had more children it got difficult to find quality safe seats to fit in our vehicles. From bulkiness , to installing, or having to buy a few different seats because the weight restrictions or kids grew a little faster. The radian car seat is amazing allows me to fit all my seats safely in the vehicle from forward facing to rear facing the set up is easy , easy installation the kids are comfortable in them and they all have their own colours and in a month or so I will be buying my 5th . For our 6 th bundle of joy finally a seat I can keep all the way through their stages . That doesn't fall apart , or get out geown

Diono Radian RXT
Our vehicle was totaled in a recent accident and we had to replace our car seat and we knew we wanted another Diono Radian RXT, so we searched the internet to find the best price and Albee Baby was the best price available. Saved a lot of money and easy process and received the car seat in about a week. Our son is very happy with his race car colored car seat and we are happy with the 10 year life span so we can get a full 10 years use out of it since we have a baby on the way. I would purchase from them again and recommend others.

Fit 3 across in my Toyota!
Happy with the carseats. They have a nice narrow fit in my Toyota highlander making it possible to get all 3 kids in the back row. They are a little difficult to get securely installed at first, (keep in mind I'm putting 3 in right next to each other though!) but after getting them in there tight it's a good fit. Kids love them:)

Diono Radian RXT
Love the Diono brand car seats. I feel like my children are so safe in this brand. My daughter is turning 1 next month and the infant car seat was getting to small for her. But really the cheap plastic of the infant car seat just made me want to get a convertible car seat for safety issues. My older daughter has had her Diono for 3 years now and it is so easy to clean and install. Love it!

Fits well with "angle adjuster"
The foam angle adjuster makes all the difference. The front seats were not accessible with the car seat until I used the angle adjuster. With it, the seats fit nicely and fit in the driver's seat in a PriusV. Love that these are narrow. Install isn't that challenging if you read instructions first and use common sense. Currently have one on each side, but will try them next to each other to allow access to a seat in the back. Love that they work for a long time for rear facing (height and weight).
ProsLasts long time, longer rear facing, narrow, low profile
ConsNeeds angle adjuster to make it work
Best UsesExtended rear facing, 3 across

Quite Comfortable for my little guy...
This seat is big! I have a minivan and it didn't really fit too well into it. It took up so much room that only I could drive the car with it installed, my husband didn't have enough leg room. So, we had to order the pad to go under the seat and then it gave us a few more inches so my husband could fit comfortably. My son is super comfortable in this chair, he was hating the infant car seat. Overall I am happy with the purchase and picked it for the excellent safety features and ratings. It will be even better when it is forward facing.
ConsTake up a lot of space rear-facing.

Buying a second one for my husband's car.
Yes this car seat is heavy. The weight of the car seats means nothing to me, safety is everything. I'm purchasing a second one to put in my husband's car because I believe in this car seat. You cant put a price tag on your child's life and I believe this seat is well worth the money. I was researching less expensive seats but ended up spending the extra to buy this one. I am very impressed.

Rearfacing up to 20 lbs stated on the side of this carseat
I bought this product with the understanding it could be used rear facing. When my daughter outgrew the infant seat I bought, we switched her to this. (The infant car seat is the best for infants because they are portable- this one can not be easily taken out if the infant goes to sleep in it.) It is so tall and bulky when it is rear facing, I can not recline or move my seat back to a comfortable position and I am only 5'5". My husband can't even have the seat behind him in. We can only use it in the cross over suv (Qx60), I can't fit it into my Passatt rear facing. Also, my daughter is average size for 1 years old (3x birth weight) at 1 years old- so she is 20lbs. We just noticed when we installed this- on the side there is a sticker that says rear facing maximum weight is 20lbs. Online it says upto 45 lbs. I don't know what's safe or not- but in California toddlers by law must be rear facing up to 2 years old- so basically I wasted my money on this. I am so disappointed. I am going to try return it- but unfortunately this was something I got for the baby shower over a year ago. I am sure this is a great option for front facing 2+ years old... but infant and toddler upto 2 years old is not good in my opinion.

Best fit for growing family
I wish I'd bought this with #3, instead of waiting until we had four kids in the car!!! This is the best seat to fit side-by-side, and I'm so glad the rear-facing lasts for so long! The instructions are also very thorough and go through everything you need to know about setting up the car seat. It is a very heavy, very durable seat and the only one I've seen that lasts for 10 years.

Diono DRadian RXT Convertible Booster Car Seat
I purchased this car seat for my granddaughter who is 18 months old. The seat is a little heavy to lift but built sturdy. She fits in the seat comfortably and is easier to get her in with the low sides.
ConsI have a Nissan truck and the car seat need the angle adjuster so that my front seats could go back for someone to sit in the front seat.

Great as expected
This is our *THIRD* Diono Radian RXT car seat. Just as good as expected - solid, sturdy, easy to use. The car seat is on the expensive side compared to many others on the market. We ordered this one after we had a cheaper car seat for one of our cars. The higher price is well worth it when it comes to saving the daily struggle with buckles and straps (meaning screaming kid).
