My friends use one and like it. Visibly it is too bulky for me (I like thin leashes without a lot of stuff going on), but the materials and function are nice.
I had a rope Kong leash for a while and LOVED it, used it all the time. I broke it in my car door and haven't got a new one lol. But I plan to get around to sometime. But it was a nice leash.
Looks cool! But I need something tough because raising cattle dogs goes through a lot of leashes lol with the grabbing and using them as tug toys when they get pissed about something Round their neck.
