Rechargeable Waterproof Dog Training Collar with remote shock E-Collar

Works wonderful on our doberman. My mom is not able to control the doberman so the collar comes in handy for her. She tells me that she only has to tone him, or use just the vibrate button and on the lowest setting too. This is a great improvement from the one that I had previous to this one. It had been dropped a few times and some of the functions did not work.
