I searched long and hard for a collar to help my goldens not to bark constantly and in particular my little Male to stop jumping on people when they come to the door. So, she barks, he jumps.I found this remote set with 2 collars and one remote. This is perfect since you cant be handling 2 big dogs, 2 remotes and someone at the door.I found the items to be in perfect new condition with clear and concise information and instructions. If you cant read, it came with pictures.I am severely challenged in anything technological so I was worried. I plan on using the beep and vibration only because I dont feel goldens need harsh discipline. But it is there for the shock if needed. Of course, despite the info saying not to do so, I had to try the shock on me. It will grab your attention but not bring you to your knees on the lighter settings.So 2 collars, one remote and a charger. The only thing I can think of to improve would be 2 electrical charging cords. But even that is not a big deal.Easy enough for me and dog mom approved.
