The Squirrel Defeater is guaranteed to be free of manufacturing and material defect for 2 years from the date of customer purchase. The warranty does not cover any damage occurred from chipmunks, raccoons, bears or any other animals besides squirrels. Hang your Squirrel Defeater so that there is at least 18 inches of clearance around the feeder; otherwise, Squirrels can stand on and reach out to grab the feeder from deck railings, etc. and will access seed ports without activating the weight mechanisms. Failure to hang feeder at least 18 inches from anything else will void the product warranty. The perches close the feeder when 60 to 65 grams of weight are on them.
