It works with no issues.

Easy to use & install. I knew immediately that it was emitting a high-frequency sound, because my teen asked “what’s that high-pitched sound”, and he was upstairs! Naturally, being older, and not being able to hear this, I was happy for the immediate confirmation.Picture was taken at night, after 2 second installation.Update: it’s been over a month now, and dogs no longer poop on my lawn! Love this!

It worked pretty well for about three months in my front yard until one morning started to sound crazily and uncontrollably. One of my neighbors couldn't stand the constant high pitch, called the police (I wasn't at home). When I got home (police was waiting) and tried to stop it, it just wouldn't let me. There's something wrong with the quality of the device... obviously not really reliable. Money waste is one thing; hate to throw things away that I thought I made a good choice in the first place.

This did a great job while it worked. The only think it did not deter was a fox…The only issue I have is I purchased it Sept,2021 and it died March, 2022.

I'm not saying they keep the cats out 100% but they haven't been using the bathroom in my yard. Bought it last November 2021 and I think it really took a bit to truly annoy them enough to realize they can choose another neighbors yard and avoid the hassle.

We bought this after our neighbors outdoor cat started leaving us dead and half eaten mice and frogs on our front doorstep every morning. This sensor safely keeps the cat away from our front door and we have had no more "treats" to clean up in the morning. Definitely worth it.
