It is designed to repel geese based on sound waves and geese in distress. This audible sound wave will repel most, but not all geese. It is probably 80% effective. There is no guarantee by the manufacturer that it is 100% effective for any number of years. Like most electronic equipment, it will last several years when properly installed and maintained according to the manufacturers recommendations.
