As of now I only have 2 9ft rolls. It works great with 2 rolls, it runs smooth. The only issue I had was locking the rolls in place. They keep sliding down. To remedy I just used a clip on the chain and clipped em together. Works great!
FAUSTO H: You can tighten the rolls up top so they will not slide down as easy. But if you make it too tight, the roll will not move up and down. You just need to find the happy medium so it stays in its correct place and moves when you want it to.
