Review title: barkfree
Product review: I tried it on the audio to see if it worked and it worked infrequently when my dog barked in the house. The barking in the house was very loud. This would have no effect out in the yard on neighbors dogs so I used it from a window. It had little effect on their need to bark but they found it annoying and would go to the far side of the pen. Bark free was not sensitive to barking and did not work unless I pressed the button on audio. It certainly was not cheap. Thank God these horrible neighbors who had dogs penned about 60feet from my window are no longer there. In this county there are no enforced ordinances.
