Bought this leash five years ago, soon after adopting my dog. It's always felt great in my hand and is only improving with age. It gets softer, but stays strong. I'm pretty sure it will last as long as my dog will. I would buy another in a heartbeat, except that I don't need to yet. I have a friend with a new puppy and plan to gift him one.
The leash and hardware are substantial. I would not recommend for a dog less than about 30 pounds, the clip would probably be too heavy. For anyone with a larger dog this is definitely a plus.
