This is our second Ruffwear Knot-a-Leash. The first is still going strong nearly a year after we got it, I ordered a new one as a backup and also because I like the newer carabiner style. Our original is pretty dirty, but is 100% intact. Threads may pull out a little from this leash, but they don't break. We play tug of war and it remains unharmed. I love the reflective material woven throughout, adds just a touch of extra visibility during night walks. The length is slightly shorter than traditional (5ish vs 6 feet) which I think is a plus. The handle is padded and comfortable. The rope material is stiff enough that it doesn't tangle as much as traditional nylon leashes and doesn't drop to the ground when slack. We use this leash in the city, in the woods, in the rain and the snow, and are 100% satisfied.
