I just tried using my "PetGentle" device on my neighbors dog. Mind you, this dog barks at the wind everyday.
Well, my neighbor caught me using the device, because when activated it flashes a light and has a laser beam. My neighbor threaten me, he was going to call the police because I was hurting his dog.
Since you can't shut of the laser beam or flashing light, it's only good to use on your own pet. Since I'd like to be discreet and I'm not looking to hurt any animals hearing, I'm disappointed there's not an option to turn off the flashing light and laser beam.
