Putting this kit together is one thing, making it work is another. The structure is well thought out. It has been combined with a notch-like design. Trying to get it to work without the balls falling out proved to be a problem, as connections would loosen when trying to tilt or tip the ramps properly. I even mounted the build on a heavy board to make things easier. Sometimes this worked, when tried again a few days later it didn't work properly. I'm very good at mechanics and engineering, so I enjoyed using those talents in a different way. This is not a product that works.
