Factee Bird Scare Devices, 3.9 Inch Large 18PCS Reflective Discs Set + 6PCS Bird Scare Rods, Double-Sided Bird Reflectors Keep All Birds Away Woodpeckers Pigeons from Your House Garden Boat

My package is missing the silver chains to hang the mirrors from. Unable to give proper review as I have tnot yet purchased chains so I can hang them

Seems to maybe work (only firest day) trying to eliminate Barn Swallows in horse barn every yr. These are definately mirror like and shiny. We will see if they work long term. Barn swallows are hard to scare away esp in the spring when they arrive and start building nests. So far, they are shiny and would scare me if I were a bird. You must mount in shiny area that gets the sun and breeze.

These work great. I had several birds who frequently visited my patio furniture. They left droppings and I couldn't enjoy the patio without spending an hour cleaning beforehand. These are pretty and deter the birds from leaving their marks in my furniture.

These did not work keeping birds away from nesting under our porch. But they are mesmerizing to look at :)

Works very well. But Not durable. The plastic discs break at the hole. It has been 6 weeks and I have many breaks. Now to be fair; they are on the back of a boat when it is docked. There is usually a breeze. But still I have to rate them as Not durable. I will be patching them with duct tape to try to get through the season - another 8 weeks. Not hopeful.
