Like other people have written we put together the stroller to fit with the Graco Snugride. After assembling I kept thinking I was doing something wrong. IT does not SNAP! It simple lays on a bar and has a flimsy strap to hold it on the stroller. Thanks for wasting four hours of life Snap n' Go! You could have just told me there was no snap to the go!I think it's a piece of junk. The wheels are foam and after 2 walks on regular terrain the wheels are pitted and falling apart. The only good thing about it is that it is lighter than our Metrolite stroller. Hope this helps!
