Doesn't affect cats or dogs
I wanted to use this to get cats to go away out front. So I tested it with my cat. She happily slept with it a foot away for 15 minutes. And just tested it with my cat awake. It doesn't phase her at all. Doesn't even notice. My ears, however, hurt from it.
It works pretty well
In all it's great
Video ads with sound after every action. Impossible to use!
Along with the ultrasound you will also listen to a video commercial of an app which you won't be able to close for 5 seconds.
