Review title: Waste of Money
Product review: The trigger mechanism is completely unreliable. Occasionally the light comes on at the tiniest of noises, apparently indicating that it's going off, but more often you can scream into the thing and nothing happens. Since it has no effect on my dogs either way, it hardly matters. When I push the manual control, the light comes on and my dogs tilt their heads, but it sure doesn't stop ANY of them from barking. I called the company and they sent a replacement, which was no better than the first. Particularly if you need something to control barking while you're not there, STAY AWAY!
