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.

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.

2nd base is a definite must to make life easier
This base is exactly what they needed to make life a lot easier. My Son and Daughter-in-law do not have to worry about moving the car seat around between cars. They both have a base and are ready to go with whatever car they chose to use.

Secure base, safe baby
Feels very secure, thanks in part to the extendable leg for support. We’ve had another type of car seat base and this one feels waaay more secure, very little wiggle. I feel comforted knowing my baby is safe!

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

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
