I like the "lightness" of the larger diameter leash and the design of the hand loop is very comfortable too.
The leash is strong and the carabiner is easy to use and will not accidentally open if the knurled nut is closed up over the opening joint.
I was able to color coordinate the leash color with my dogs Ruffwear collar and walking harness.
Overall, this is a high quality leash as is all of the Ruffwear items I has previously purchased. I expect them to last the life of my dog!
