KH-Security Ultrasound Device with LED and Blinking Light

With this multifunction ultrasound device, you can protect yourself against aggressive dogs, pesky mosquitoes and the LED lights your way in the darkness.
The use of the ultrasound device is self-explanatory thanks to the corresponding pictures:
- Dog head: By holding the button a high tone is emitted, which is inaudible to humans, but acts as a deterrent for dogs. The sound is only emitted when the button is pressed.
- Mosquito: By pressing the tone is activated and is switched off again by pressing the button a second time. The sound is for people audible but not disturbing and effectively keeps the mosquitoes away.
- Light bulb: By pressing the light bulb button: the LED lights up with a constant light. Press twice: the LED flashes and push three times the lamp turns off.
