I just recently purchased this 16ft dog night walking leach and I have to say that I really like it alot. I have a boston and he is so strong i like that i can lock and realease it as often as I need to give him more walking room ahead of me or just stop him from going any further. He at times tends to think on his walks he is in control. With this leash I am in control and he learning fast he cant pull me and just go where he wants to. I like that this leash is bright in color for night walks I have had no issues with it tangling on me . I am extrememly pleased! I for sure would recommend it to anyone looking for a good leash!
