I got mine about a week ago, slipped the battery in, and prepared to be amazed.
But, for some reason my pooches were quiet for days. No unexpected outbursts, no prolonged barking at leaves blowing across the lawn, nothing...
Then company came over.
The first time I used it, I said, "Hush!" pointed it at them, and pressed the button just once. Cricket cowered and hushed. Zaccheus barked at it. I did it again. Again, Zacchie barked, but just once this time. I did it once more.
Silence.
Much praise.
Now, when I actually have to use it, (most of the time, I just have to show it to them) they are quiet after the first use.
Amazing.
Best $10 I ever spent.
