Aside from seeing mice around I mean 
I have them in my shop and have no mice, but as with everything I assume they will break and go bad. Yeah the little LED will glow but how can I test them ?
An ultrasonic mike hooked up to an O-Scope ?
Do they make such microphones ?
And yeah I know most say they do not work but they work for me. So far anyway.
