The unit after installation works great though the instructions are quite vague. There is no list of hardware you may need besides the top swivel and furler. I added a pulley on the deck and guides to a cleat in the cockpit. It does work well though. I tried it on a genoa and jib sail and it worked splendidly. I recommend it as a lower cost, small boat unit. My boat is a 22ft Sirius.
