I hesitated getting a leash like this just because I thought my regular leash worked fine. If you're a runner with a well behaved dog, GET THIS LEASH! It's awesome. Your hands are free to hold a water bottle and you avoid cramping up and avoid bad posture. The leash moves from side to side on the belt part so if your dog chooses to move around you, you won't get yanked around. It's built sturdy (probably even sturdier than our regular leash) and it's a great price.
