easy to use, and works exactly as expected

We purchased the Britax Aspen Infant Car Seat Base for our second car. It is compatible with the Britax Willow Brook S+ Baby Travel System. The base feels very solid and secure. Installation is straightforward, and the ClickTight system makes it easy to get a tight, confident fit in the car. Once installed, it doesn’t move around, which gives great peace of mind. The level indicators are clear and helpful, making it simple to ensure proper positioning. Attaching and removing the car seat is quick and smooth. Overall, it’s reliable, easy to use, and works exactly as expected. I would definitely recommend it, especially if you need an extra base for a second vehicle. ... show more

Fits willow s
Fits the willow S! Just without the bar that comes with the seat originally. But still works great.

Excellent, but tricky at first
Great once you actually know how to install it If youre sort of an idiot like me, it gets difficult, and the instructions don't help. What you need to do if you're using the seatbelt for install is slide it not under the handle you pull up, but even lower than that. There's a gap that comes out when you pull the handle up, allowing just enough space to run it through. From there, you push it back down to lock. Once you have it down, it becomes second nature. Super easy to take in and out, it's just the initial install where you might have some confusion ... show more

Easy to work with
We bought the Britax infant car seat and stroller first, and later ordered this base for the 2nd car. It works great, is easy to install on the car, and to move the car seat in and out.

Easy to install!
Easy to install and stays secure. I know some other bases gradually loosen but I have never experienced that with this!

Fits perfect
I wanted the adaptor for my personal vehicle so I wouldn't need to switch car seat bases between cars and risk wear & tear or hasty installation risks when alternating vehicle trips with the baby. I Love this car seat/stroller system.
