Bullet point: _x000D_ 1. Made of high-quality stainless steel, corrosion-resistant, light weight and easy to start in the breeze. _x000D_ 2. Wind power is used as the power source, and unique ground bearings are used at the same time. The principle of optical reflection is used to dispel the birds, so that the birds do not dare to approach, nest and perch. _x000D_ 3. Not only ensure the smooth power lines to reduce line failures, but also protect birds. _x000D_ 4. 360 Degree reflection angle to drive away, 15 to 20 laps per minute, the bird-repelling effect is quite obvious. _x000D_ 5. Long service life, can be used for up to 10 years. _x000D_ _x000D_ Description: _x000D_ Material: Stainless steel _x000D_ Size: height: about 17cm, fan diameter: about 30cm _x000D_ 10cm = 3.94inch _x000D_ Swinging wind: 0.5 _x000D_ Bird repellent range: 3.6m _x000D_ Service life: more than 10 years _x000D_ Power supply: using wind to drive the principle of optical reflection interference _x000D_ Scope of application: transfer pole towers, towers, stations, farms, orchards, fish ponds, warehouses, large workshops, food processing plants, airfields and old buildings, etc. _x000D_ _x000D_ Package included: _x000D_ 1 x Stainless Steel Wind Power Bird Scarer _x000D_ _x000D_ Note: _x000D_ Due to the different monitor and light effect,the actual color maybe a slight different from the picture color. _x000D_ Please allow 1-2cm differs due to manual measurement.
