1. Principle 1. Use solar energy to charge and charge 2. According to scientific research, animals are very sensitive to vibrations and tiny vibrations can be felt. This product is therefore low on the principle of the transmission of vibrational waves, which makes it unbearable and escapes the scne. 3. The mouse has acute alertness, so it has a fixed route of activity, and a slight change will immediately cause alertness. After attacking, they will live this place for a long time, which is also the reason why ordinary mthodes can not gurirate the rodent infestation. On the contrary, by using the fine oue characteristics of rats, supersonic and lectromagntic waves are designed for sensitive people and sensitive sound segments of rats, so that they cannot be hidden. There is no way to hide. 2. Area of use This product is suitable for open meadows, parks and other open spaces. The effective gate is about 300 square meters. The closer the effect, the better the effect. It is recommended to use 2 3 products if the garden is relatively large. for better effect. 3. 1. Special intgr device for transmitting sound waves and vibrational waves through the ground, making snakes and mice uncomfortable, in order to remain the cart of the scne and achieve the driving objective 2. Use of solar panels to provide electricity and high quality integrated cological rechargeable batteries, which can store enough electricity 3. This product is easy to install, without any radiation or damage to the human body, you can use it with confidence 4. IP65 protection, high protection against water and lightning 5. The mouse has acute alertness, so it has a fixed route of activity, and a slight change will immediately cause alertness. After attacking, they will live this place for a long time, which is also the reason why ordinary mthodes can not gurirate the rodent infestation. On the contrary, by using the fine oue characteristics of rats, supersonic and lectromagntic waves are designed for sensitive people and sensitive sound segments of rats, so that they cannot be hidden. There is no way to hide. Effectively expel hide mice in dead ends, covering a range of about 50,100 m2. Name: Solar repellent carr for mice Solar panel: polysilicon 4V or 45MA Vibration frequency: 400-1000Hz Battery capacity: 1.2 V or 600 mAh NiMH Vibration last: Vibration 4 seconds, interval 30 seconds Product matrix: ABS and PVC Working principle: buzzer intgr (sound waves) or motor vibration and ground rsonance or to loigner Note the waves low-frequency sound, safe for the human body Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
