I tried it at BRU and couldn't get it to fit. The girl who was helping me said she didn't think it was compatible but I don't think she was completely sure. I ended up getting the Joovy Caboose because I knew for sure it was compatible, it doesn't cost much more and it had better reviews. I'm very happy with it so far!
