I don't think this is working, much. Mice is still running around one year later.

I can still hear the squirrels gnawing in the attic on cold nights. The gadget has been on 24/7 for more than a month.

Work as advertised. Mice are gone!!!!

Doesn't work. Good thing I have a cat--she's caught 3 more mice since I bought these and plugged them in.

seem to work great

Great

Don't work as claims

While I cannot say I heard anything from these, I had awful sinus pain any time I was in the same room. I tested several times to make sure this was the cause.
