it works great and I would buy it if it was not a yearly subscription. Ads pop up and make it hard to use quickly when you need to. Uninstalled to buy one out right.
The frequency of most dog whistles is within the range of 23 to 54 kHz. Look it up your self. I did. This stopped short of 23 just like all the others I tried.
This thing is so terrible. You wouldn't believe. All it did was make my ears bled!!!!!!!!@
