So everybody knows, this is how my reviews work. I will copy information about the product from Amazon, so you get the information from the companies own mouth about the product I will add a picture, then I will give you an opinion about the product in my own words. I think it is important to have the information from the company and an unbiased opinion, so you know the most about each particular product.
We received this product for free, the review is my own. I have a chain that I use (around my neck) while beer vending. This whistle fits perfectly on the chain. My dog pays attention to this ultrasonic whistle. He barks too much and does not listen to my voice all of the time. When I used this whistle, he gave me his attention and listened to me when I told him to stop barking. I will use this whistle to train my dog in other ways, this is a great tool.
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
