Tested on mice recently

A little early to give an opinion of course since it is recommended a minimum period of 15 days to see the effects.
To date it's been 3 weeks and no rodent in sight.
I advise to put on one level house (3 volume levels) because the noise on other levels is strong enough and embarrassing.
In the garage or cellar no problems for the sound level.

After almost a year of use, plus a single mouse at home! Coincidence? In any case the result is there
