I bought this item as a way to keep rabbits out of rose bushes. I was skeptical when I bought it, but thought I would try it.Took us a while to fine tune the motion sensor and the sprayer. We have it by our front porch, and didn't want to spray ourselves as we walked to the front door!We've had it set up for over a month, and as far as I can tell, the rabbits haven't gotten close to the roses!Word of caution: If the spray range is set too narrow, the sprinker tends to get stuck and doesn't move back and forth. Setting the spray range wider seems to correct the problem.
