### ⭐⭐⭐⭐⭐ Does the job!
*by R***R on October 10, 2022*

Works like it should. Buy if you need!

### ⭐⭐⭐⭐ Nuna Infant Car seat
*by B***S on December 31, 2022*

Easy to connect and remove but the angel for infants is too inclined. It feels secure and sturdy, it’s just the angel that really sucks.

### ⭐⭐⭐ They work...sort of
*by N***E on January 13, 2020*

They attach to the stroller and car seat but I don’t like the angle that the car seat sits. It seems too inclined for a newborn.
