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 Nicole Her

I bought this device to control my dog's jumping when greeting visitors. Even though it only weighs 25 pounds, it's too big to jump on my young grandkids, and let's face it, not everyone wants a dog to jump on them. I won't say he recovered but I will say his jumps got worse and I hope we can do it eventually. My only complaint is that the power button isn't momentary. It takes about 3 seconds to turn it on, which can be a long 3 seconds if you want to fix things right away. He's on my doorstep, so I'm ready. Unfortunately due to Covid I don't have as many visitors as I used to and this has reduced the number of training opportunities but I see an improvement.
