Ok –
I love Diono seats (even if they tend to be complicated to install). This ine is good but when the headset is up and the seat is in the middle of the back seat it blocks the rear view mirror since the wings are very big (so they provide more head protection to the child). I was able to lower it an inch and it is better, but when my son grows i will have to move this seat to one side.

Recently switched to booster seat as the car seat seatbelt were out of place and too low on the shoulder and it was time to get a new one. The car seat was seat to install and assemble. I just did a quick video search on website and can figure it out easily. The seats are wide and the head pieces are in great position

The daughter outgrew her baby car seat. We researched and this one had some great features, looked nice enough, and can eventually just become a booster, giving it a little more life over the long run- but in the meantime it provides the head guards and backing while she’s still of the size where those are needed. Cup holders are a must, and this has them!
Once it’s securely anchored, she’s using the vehicles seat belt herself, and usually manages fine in the Odyssey, but struggles to reach the buckle in the CR-V, so as I’m wary of getting an extension, I just buckle her in still.
As mentioned, I bought another for the other vehicle- just so I can avoid moving this one back and forth for any quick trips or daddy-daughter outings. Once the son is older and needs a bigger seat, I may move the second back to the van, but would strongly consider buying at least one or two more just for convenience.
