I honestly purchased this just to try. It was cheap and was searching for a tether for my impact. I love it. I have dropped impact on purpose a few times and notice the spring like action help keep my from being yanked on. Good tool. Should have bought a few more
When I rig I normally use 2 tools the most. So this allows me to switch between both of them without having to keep disconnecting and reconnecting every time I need to switch between them. It saves me a bunch of time.
