Query: worth the price

I was a skeptic. But after cleaning up copious piles of cat poop in my 5'x10' concrete yard, I was willing to try anything. I had already tried black pepper, red pepper, and orange peels, and I didn't want to put out anything that would hurt the cats. My neighbor recommended this. It arrived quickly, and once I put it up, it immediately began repelling the alley cats from their favorite spots in my yard. It's been out there for about 4 weeks, and I've only seen droppings from the cats maybe 4 times since then.
