Reviews

Fun! Great directions, but the parts fall apart more easily than I would have liked for how much hard play it gets as a cannonball launcher.

It was bigger than expected and my 3 grandboys had a blast!

my 8 year old had a blast putting this together and has spent all day playing with it! totally worth it!
