The top half of the harness is very flimsy as well. The vest is made poorly and does withstand much tension at all.

Love the blinking glow in the dark leash! I am lite up and so are the dogs i walk with. Holds charge well.

Was great first 2 months. Tried charging them again and had same problem. Now the other three are super-dim even on a full charge. The lights have a serious defect.
