I had a classic harness before, the dog had gotten used to pull on the leash and rely on the harness. Result, walks it became painful, I ended up having a sore arm to force the curb. I tried this harness, and frankly the difference is amazing, my dog has more traction reflex and when she still pulls the clip the leash in front forced him to deviate to the side and suddenly it cuts in its tracks. I am very satisfied. Only downside (and it cost him a star): the harness relaxes at progressively with each new trip I must readjust.
