I think its a great leash! It feels very secure, definitely very light. I wish it was a bit thicker, my dog used to be a flight risk, so a thin leash that he can bite through easily does make me a bit nervous, but he wears two leashes and hasn't bit one in over a year.
I wish the traffic handle at the bottom was a bit easier to grab. It takes me a second to open it up and get my hand through, which defeats the purpose if I need it quickly. It's really just an extra flap of fabric, and less of an actual handle.
I only buy leashes that have that specific style of padding, they are super comfortable and easy to wrap around your wrist, making the leash feel very secure. The clasp is also very strong and I have no fear of it unclipping, even without the safety lock on.
My dog's other leash is slightly longer, so I wish this came in a few other lengths, but overall the length is very good. It's 5 ft for those wondering. I couldn't find the length anywhere on the website when purchasing except for the comments.
Overall, it's a leash I will continue to be using, I'm very happy with it :)
