Works as good as the elephant repellent I use on my yard. Have yet to see one or any of the large "leavings" indicating one has been around.
Wish you had a trike, I'd sell one of my parking brakes to you
Seriously, I do not believe these are worth having.
I read somewhere they are not designed for motorcycles & there is argument that they do not work, but I'm planning on getting them anyway as our vacation home is deep in the woods, where the deer and the skunks roam.
