Bigger than I was expecting. Looks well made. Time will tell if it keeps the birds away.
No more birds pecking at the roof at 6:00 AM. I don’t need to run outside with a hose anymore.
We installed it with flashers, ultrasonics, and netting. The pigeon problem is 99% gone. Only a few show up and leave quickly.
I bought this with low expectations, but it actually works. It needs to spin to scare birds. I mounted it near the fan on my roof to catch the airflow. It spins when the fan runs or when there's wind. It even keeps the woodpeckers off my orange trees.
