not effective for raccoons and the blinking is really annoying

These didn't work for me. The lights blink from dusk to dawn, that doesn't simulate a predatory animal's eyes to me. Apparently it doesn't to raccoons either because they kept knocking them over on their way to trashing my lawn. It also doesn't look great to have red blinking lights on all night, it made me feel like I was in a prison yard. For the record I've tried: netting, double netting, moth balls, soap flakes, pepper flakes, ammonia, motion sensor lights, these red lights, and dog poop. The best solutions seemed to be the bird netting, pepper flakes, motion sensor lights, and dog poop. None worked completely though, we had to seal off all the hospitable hiding spaces. I returned these. For what it's worth, the quality seems good.
