This makes life a lot easier with a small dog that refuses to continue to walk halfway around the block on hot days. But I wish it came in other colors, besides black. In low light conditions a bright color plus reflective trim would be nice. And trying to see inside a black pack to put the black stays into place,  feeding the ends into tiny black loops, is almost impossible for somebody with 60+-year-old eyes.    If not for the black color, I would given this five stars.
