Bests & Worsts Reviews from Amazon

This "deterrent" has had zero effect on my neighbor's dogs. In fact, they run right up near the thing (within 2 or 3 feet) and seemingly bark AT it. And they don't stop. They just seem to be annoyed at it rather than learning not to bark. I am not impressed with this product and question the legitimacy of the 5 star reviews. I do not recommend this item. The merchant, Key Products, was excellent, however. I did receive it within 4 days of ordering with regular shipping and I would recommend them. Just not for this product.
