Yes, I have ex.perimented with those devices, but for cats, not for mice. In Hawaii, our neighbor was claiming that our cats were stinking up his yard, so I purchased several of the high-frequency sound transmitters based on online reviews that claimed they were effective in repelling cats. The frequency on the devices was adjustable. I set the frequency to "cat" and placed four of the devices in the areas where the neighbor said the cats were causing a problem.
The cats ignored the devices. But I noticed that I could hear the devices myself if I did not set the frequency high enough. Also, the setting tended to drift, so eventually ("eventually" here meaning "within a matter of days") all the devices became audible and annoying.
(Additionally, in my "adventures" under the house while setting up the high-frequency transmitters, I noticed that most of the neighbor's drain pipes, including the main sewer drain, were leaking. And stinking. And likely causing the smell about which he was concerned. I also discovered that his tenant had been tossing the remains of his shrimp and fish plate lunches under the house! Another source of a quite impressive smell! Ah, Hawaii life! It is not always as blissful and idyllic as it appears on the surface!)
They're not dolls, they're action figures!
