We really like the snack pack compared to buying a snack tray which for the snap duo doesn't hinge open like the belly bar. It does "spin" a bit if you put heavier items in it so make sure it's on tight. It's also a bit wide for the curved bar so it doesn't sit quite as it's pictured (straight across). I do fold it right up with the stroller which I love. Overall we really like it, just a few small things we noticed!
