Works great! I installed it 2 months ago because the roaches were moving around my kitchen in a big way. I didn't want my food to be contaminated with them so I bought this and it works. My dog is sensitive to noise but he doesn't hear this and care nothing, it works great for getting rid of cockroaches in my house.

I purchased these for both the homer and the office. We wanted to get rid of all unwanted friends and it is amazing how well they work. We have not had any insects, pests, or critters in either lcoation since we put them in. They are simple and easy to use and they do the job better than I ever thought! Now not only do I have happy workers, I have a happy family as well that isn't yelling for me to "GETIT!!!"

I purchased four of these, so far these have been in use in our home for a little over a month and there's no evidence of mice inside at all. We do catch plenty of mice in the traps in the barn so I know they're around but they seem to be choosing to stay out of our home which is exactly what I had hoped.

Installed this easily on the outdoor outlet, within 3 days all mice were gone and they've stayed away!

My daughter in college called me in a panic because of infestation in her dorm room! I immediately researched the most effective solution and found your product! She just plugged in and the issue was resolved!

I didn't know what to do or how to handle mice without possibly having to spend a fortune on pest control. Pest control company is expensive. Then I tried this, within 24 hours I did not see one mouse. I am SOOOOO beyond happy with this!
