Doesn’t work at all, reinstalled it a few times and still doesn’t work
This is a basic sound frequency generator. I use it to deter mice, who otherwise love my house! One improvement would be the ability to use it in the background. Also, it sometimes doesn't want to start. I often have to turn it off and back on 2-3 times to get it started.
