Review on MODUS Anti-Barking Device with 3 Ultrasonic Modes - Effective Dog Training, Rechargeable via USB, LCD Display - Control Range of 16.4 Ft - Perfect for Outdoor and Indoor Use by Ali Anjani

I have found this to be a very effective training tool for my small dogs! I have people just walking around and my dogs start barking and growling. Now when they do that, I use the remote control and the sound immediately makes them stop barking and they actually leave the room. My cats walk too. It's also really helpful when people come into my house for work, I push a button and they bark less and eventually stop because of the noise. I can appreciate something like this that changed my bad habits so quickly!
