Simple to use adapter -- clicks on and off very easily and great to use the car seat to rear face the infant in the stroller.

Bought this as a gift and while I was putting all the pieces together with the stroller it was pretty straight forward. Attaching the car seat was a little tricky as it wasn't as easy to line up without fear of the seat falling off before being clicked in. I'm sure after doing this a billion times, you will get the hang of it, but my first few tries took longer than I expected. Also to not, they have to be removed before folding the stroller up. Somewhat of a design flaw in my eyes.
