I thought it wasn't working well until I realized that the 9v battery, which comes with the unit, was tightly wrapped in plastic and not plugged in! When I first opened the battery case, I saw that it had a battery and it looked like it was plugged in but my dog didn't react the way I thought she should. After careful inspection, I found the problem. Now my dog responds and I hope my ability to use this tool will bring me the results I want. So far, so good!
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
