good price / quality, works well, it's effective, somewhat sadistic but certainly our dog is no longer attached to the chain !!!! I prefer. He and very quickly got used to the product and "regulation". least: -Notice in English, not in French -thread very fine, not solid, -No battery (battery) inside the package, -pile 9V, maybe a little high for a small dog, no differentiation according to the dog's size !!! -collier "coarse", very discreet for a small dog (our dog was already accustomed to a collar) and we free the night of this object because it is enclosed in our basement.
