First off ... very impressed with the construction. Much heavier duty than the previous bungee coupler we had that lasted a year. The color is loverly and easily visible and the reflection strips are a nice touch for dusk walks. The metal clasps seem well constructed and should last ... that's where our last one failed is that the one clasp slider to open and close it broke.
We put 2 x 70lb dogs on it with no concerns. Excellent purchase and pricing.
