Poor quality product, in less than 6 months of very light and occasional use the bungee rope (cord) is worn out and needs to be replaced. Proform only gives you 3 month warranty for labor and parts at least this is my case upon registering the product. I could try to change the bungee rope and it cost between 200-300 dollars to buy the part.
