De mal gusto que te muestren algo armado y que te manden puras piezas sueltas, no puedo armarla, mal producto no vale la pena pagar por esto.

Birds are not afraid at all....

surprisingly they seems to work , seems to scare off assorted neighbor birds, the flashes make humans jump a little too, uses in garden and fruit trees, needs direct sun to be effective I think it pisses off the mocking birds but everything seems to do live in the great Mojave desert

These really work. Every year the birch try and build a nest on my back porch lamp. It can't support a nest so I end up with piles of mud and hay. I tried these and now I no longer have to go out and clean up daily. The birds have stayed away and still play in my backyard. Perfect

Easy to assemble. Very light weight. I hung them on the outside of my barn, and had to modify hanging process. Hangers are flexible enough to get creative if required. They make a bright flash when twisting in the sunlight. I hung one inside the barn. It isn't as effective without sunlight, but I suspect twisting motion might scare birds away. I started having a problem with pigeons, but haven't seen them since hanging the discs.
