We had to get this type of adapter as we lost one of the two separate ones that came with our stroller and a car seat. And I've got to say that this one is so much better than the previous ones... so much more stable and easier to use.

The Nuna stroller came with the infant carrier adapter posts, but I found the ring adapter is much more easier to secure, load and unload!!! I am extremely pleased to have made the additional purchase! Very much worth it!!

I purchased this adapter as an additional parts for a car seat stand. It is must have item for who use the car seat stand. Very useful.

Purchased for my Nuna Mixx stroller and Pipa car seat. The ring itself is super quick and easy to click onto the stroller , and makes taking the car seat in and out of stroller a breeze. Totally worth the cost for the convenience it provides.

Made taking the baby from the car to the stroller easy! Simple to interchange w/ other Mixx2 adapters.

The adapter is super useful.

If you have the Nuna mixx you have to have the ring adapter. It makes transition from the car to the stroller a breeze.

Fiddling with buttons to release car seat from standard mounts typically takes a few seconds to a full 30 seconds frustrating fiddling (just when you need it the least). This adapter, in and out, no fiddling, no frustration!

Using the ring for the infant car seat is much easier. Just one click and it's done!

Connect this to my mixx2 stroller very easy to get out and into the car. Makes life easier.

As others have echoed, this ring adapter is a must have for use with the Nuna Pipa and Mixx2. Only gripe with Nuna is that they choose not to offer this standard with the stroller.Was reluctant to purchase this initially, but after I threw my back out contorting to different positions in getting the car seat on and off the stroller and into the car, decided the $50 ring adapter is worth it. And it has been.A breeze to lift/place the car seat off and onto the Mixx2 stroller.

I bought this to go with the nuna mix Stroller , very easy to install, folded with the stroller, worked well with the nuna pipa infant car seat

This ring adapter is a perfect addition for the Nuna Mixx2 and Pipa combo. Super easy use with only one hand!!!

This is a necessity for ease with use of the Nuna PIPA car seat! It is what makes this travel system a real snap... literally! It allows you to just grab handle and push one button to release car seat, and makes it easy to snap it on to stroller.

Please get this adapter if you have a nuna pippa car seat and nuna stroller. It makes it so easy to put it on the stroller and take it off of it. You can fold the stroller with it on it too.

I like the ring adapter better. It's steady and holds the car seat to the stroller like a glue.

this adapter is so much better than the clips that come with the stroller. You can actually remove the car seat with the push of one button. I'm only frustrated that this piece didn't come with the original purchase and that we had to spend more to actually have a functional stroller.

This is much better than the adapter that came with our Nuna Stroller. One hand on the car sat handle and the other to release the lock instead of the awkward two handed lock release.
