My boy has big problem is like to go in the trash and it makes the house mess. But now the collar solves my problem. the seller sent me a video about the collar , so it is easy for me to set up the product. Once I set up vibration to train him, but he was learning not very well. As a result, I change the mode to dual Vibration. It works better than before. Also the collar is rechargeable, and can hold charge much longer than I expected.
