Resonant ultrasonic wave, SPL cavity sound wave, 10 seconds automatic frequency conversion, voltage overload protection, breathing electromagnetic wave, increase driving effect

This ultrasonic repeller is designed with frequency conversion, including the frequency that mosquitoes, mites, mice, and other small insects are offended. It is multifunctional. The frequency changes every second. In addition, the indicator light is a cycle of breathing every 40 seconds (through light waves to enhance the driving effect)

Ultrasonic driven products are not harmful to humans, cats and dogs, and there is no radiation, please rest assured! Ultrasound can actually be understood as ordinary sound. It’s just that the frequency of the sound waves disgusts certain animals. Just like when we hear the car whistle for a long time, we also feel disgusted and want to leave. This is how we drive animals away.
