“This is a wonderful product for keeping unwanted ants and other flying insects out of your birds nectar. These work great! Keeping the nectar clean is good for the birds.”
“They are overpriced considering what they are. They are not durable and stain easily, not sure if it's black mold or other fungus, otherwise they function as described and are effective keeping the bees from the necter. They are easily lost if not mindful when cleaning the feeder. I get about one season (3-4 months) from a set.”
