These are test goods that we have produced as a prototype. So the design is not on a professional level. But functionality is of course 100 percent. So the price is more for the material... 

Kuna clam, tchor,rodent, outdoor surfaces, 303/2X repro Maxi ultrasonic pest and insect scare, a proven novelty.

Laboratory research has shown that certain ultrasonic sound waves attack the auditory and nervous systems of most common pests causing them pain and discomfort. 140 decibels of sound pressure. Pests give up their source of food, water and shelter and try to dispense with the area where ultrasound is present. The device emits tuned, irregularly long, ultrasonic waves with irregularly long breaks

These highly intense sound waves are outside the range of people's hearing and most pets such as dogs, cats, fish, birds and livestock. You may hear a crisp in the speakers, which is due to the speaker membrane hitting the air and creating the crackling. The speaker is fully scuffed, but our human ear can't hear the frequencies. Children under the age of 20 can hear the incisive tones within 1m of the device, if it bothers them, it is advisable to keep the device out of their hearing range.

So the technology doesn't harm cats, fish, birds and farm animals.
