I ordered two by mistake. I would have kept both if the device had an effect. I returned them both after ten days but never heard from them.
I bought them to contribute to excessive barking. I used them exactly as suggested but neither of my dogs responded in any way. They did not seem to recognize any difference and continued to bark.
Most disappointing is that I lost money on two devices since one was ordered by mistake.
I returned them with a letter, by priority mail. They did not respond and my attempts to reach them by phone failed.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
