Great quality
Very easy to install. This is heavy so it’s a nice piece of mind. The corresponding car seat clips right in and is perfect. The leg style design was nice because it felt like it was counteracting the weight of the car seat. These are a little pricey, but worth it.

Fast shipping
Love our uppababy carseat and we got extra bases for different cars. Shipping was quick. Set up can be a little confusing if you don’t read the instructions

Our second base
Easy install – we got another because we needed one for a second vehicle. I like that it has the leveler and the easy to tell “red” and “green” to show if the seat is installed securely

A must have
If you have more than one vehicle, it is super convenient to have an extra base. I like the added safety feature of the arm. Installation was easy and the fit is always sturdy with uppababy. I can’t have a car seat that isnt easy to install or my husband would give up.

very Solid, easy to install once you figure it out
Works Great, easy to install in my sedan but tougher in our SUV. Once you get a hang of it, its pretty easy to put in quickly. It feels really secure and looks minimalistic

Safety First
My son and daughter in law bought the Uppababy Aria car seat and this base allows me to take my grandson without switching seats. This seat is a little duffucult to get installed, but it gives you confidence your baby is going to be as safe as possible.
