Mine broke after 6 months . Crap customer service too . <| sep |> Way more fun then $ 10 should get you , definitely worth the buy <| sep |> Broke my leg at summer camp . My patella popped out and I tore a ton of ligaments and tendons . How to spend the night in a tent and I was not given any pain medication , but it doesn ' t stop there . When I get home we go to doctor who just tells me to just relax my leg until it ' s healed . It doesn ' t . Every other week we tell this doctor about how I have pieces of cartilage locking my leg up . Doctor still doesn ' t do anything . A year after the accident we switch doctors and 3 days later I ' m in total knee reconstruction surgery . After about a year of physical therapy my walk feels normal . Tldr Had a dislocated knee for a year .
