Upon delivery, the package containing the pulleys was opened and a pulley was missing. The replacement pulley wasn’t shipped for nearly a week. The upper and lower wall mount brackets are not square and I had to use large washers to act as spacers to fill the gap between the brackets and wall. Lastly, one pulley space on the multi pulley bracket is bent inward. This is causing the pulley to rub and is quite audible. Overall, the product works. The system lacks smoothness but I believe purchasing better pulleys would improve the experience. Think of it as a solid base and you can add upgrades to make it better. I think I got a lemon and will make the most of it. One other consideration is the 2 to 1 ratio setup. Research and understand what this means and see if it’s right for you.
