Used it the moment I received it. Was pulling a small gauge signal wire above the t-bar ceiling line and the hook came off with out much effort. It did not get caught anything. Decided to keep it anyways. Everything else looks well built. If you are planning to pull cables with this, check the line hook for craftsmanship first. By the way, it's also hard to turn the wheel to retract the fish line. Maybe it will loosen up overtime. .
