Waste of $1 – Dog Whistle Review

Just get the free version. It does affect dogs. The upgrade for $1 is useless. It doesn't allow you to adjust sound grew in any way. It will not allow turn on or off bark detector. Bark detector is permanently off. I emailed them about the issue and offered no help. This is what happens when you do business with "The Crooked Chinese. You can really only trust them in business only up to the time you pay. Once they get your money you get nothing further. Just buy a "Bark Off," As Seen On TV. It's $7 on eBay and does work. Yes is made in China but no upgrade option. The U.S. Company who contracted with them has already done the negotiation and product is what it is.
