No need for nets
The birds like these fat balls. I would have scored more highly if they were not in nets. Birds can get their feet caught in plastic netting. I cut the nets off before putting the balls in a feeder.
Net nightmare
As a product this is wonderful. Birds love them and its great price. But unfortunately it is a nightmare for environment. There way too many nets. Would be wonderful if they get rid of all the individual nettings.
