I am a zip line guide and we use zip lines and pulleys for our braking system. They hold up well after a couple of weeks and are very grippy when I have to pull the leash. They were under $20 when I bought them and now they're over that price so I'm not sure I'll buy them again but I'm very happy with this purchase. Update: As they started to wear out, they fell apart within a few days. They were delivered on June 28th and have been completely destroyed and unusable since July 28th.
