So far it has held up to my standards. I tried it on myself before trying it on the dogs to see what strength it should be. And even only level one on the shock setting is plenty. I really like that you can turn the collar and the remote off to save battery life. And the lock feature comes in handy, because with my last collar I would accidentally beep it and the my dog would look at me like what did I do wrong. So overall, great product!
