Heavy, but easy to install
Bought 3 of these for my kids age 3, 4, and 11 months. Pretty easy to install, they don’t move at all when I try to shake them in the car. The cushion where they sit is super comfortable and soft. We were a little confused on where the cup holders go but eventually figured it out. Only complaint is the weight! They are pretty heavy. I also like that they can fold down and fit in small spaces.

Saved my sons life
Believe me when i tell you that you get what you pay for! I nearly didnt purchase this seat as the price was steep, but something told me to do it anyway. Not long after, i was involved in a horrific accident on an interstate that ultimately sent my car rolling 3 times and my infant didnt even have a scratch on him. Every first responder there asked me about this carseat! I truly believe it saved my sons life. 10/10 recommend anything DIONO brand!

Space saver! Toddler approved!
Love the car seat! My husband and I have used the evenflo 360 revolve gold since my daughter turned 1. She’s 3 going on 4 and we have a baby boy now who will inherit her revolve 360 seat. We decided to look for a car seat that was easy for my toddler to get in on her own without having to carry her into the seat and a car seat that was a space saver. This one did the trick it’s so much leaner and easy to adjust the buckles. My daughter does it on her own compared to her old one. What I will say is I don’t move the car seat at all so weight wise I wouldn’t be able to comment but when installing it wasn’t super heavy but it felt super sturdy. My only complaint is the cup holder wish it was built in but I understand it’s detachable to save space but works well! My husband didn’t have any issues with installation of the car seat he said it was straight forward for forward facing. One last thing my daughter’s head doesn’t hang when asleep it’s very rare compared to her revolve 360 that would occur always.

Do not buy this seat.
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.

Car seat for life.
Very sturdy and seems to be really safe. I like how long we will be able to use this baby seat. Difficult to install but after several tries we got it in. My car is a little small (compact suv) but I think most cars will be tight when it is in rear facing position. Overall happy and will likely buy another for the other car. Did not want to have to worry about buying a different seat for different stages of life so invested in this one.
