Seems To Be Effective
You never really know, but it seems to be working as advertised! Cat crap in my vegetable gardens has been greatly reduced to a bare minimum. I happen to have an ideal installation point which funnels into my yard so there's that. I have seen at least one neighbor's cat turn away from it and have not heard my motion sensor go off as often as before the install.... (Even though this review is listed as "unprompted" I was actually encouraged by the manufacturer to leave a review here.)
