Powered by solar energy, the Broox repeller automatically recharges under the sun, making it an eco-friendly choice. Moreover, its waterproof design ensures worry-free outdoor usage. When the calls temporarily cease and no predator is found, the arriving birds are frightened by the possible danger and disperse.
