This is a powerful mosquito sound generator. It generates powerful high-frequency sounds of about 12kHz to 40kHz. High-frequency sounds below 17khz can only be heard by young people. People over 50 years old cannot hear these sounds. It is also a frequency that dogs and cats dislike.
It can be used with 100V to 240V. The outlet is US type. There is no switch, so it works immediately after plugging it into the outlet. The frequency can be changed. It will be set to about 20kHz and shipped. A simple instruction manual is included.
