If you see this on an ad on Facebook don’t buy it. It is a waste of money and does not work. I bought one and it worked once and then it never worked again. Then I contacted their website and got no response. Then I threatened to put out this post on my blog and they sent me another one. This one did not work at all. This was a waste of $50+ dollars. This is supposed to help you control the dogs’ barking but doesn’t work. Don’t waste your money I will tell you the thing doesn‘t work. I have talked with other consumers and most had the same story I had. A waste of money and you won’t ever get it back.
