Amazing results!!
I was hesitant to purchase initially, but talking with the great guys you have on staff helped me to choose wisely. My dogs howling took only a couple of days to be totally eliminated, and that was using the lowest setting. It doesn't hurt at all, my son tried it!! I think it's more the warning sound that has taught my dog to stop the behaviour. The electronic counter is always on zero now when I return home. I love this product and highly recommend!!!
