I got this machine in about two weeks that is not bad coming from china,installed the thing in my car,connected the 2 wires,and pressed the on/off switch after that I choiced the second gear the one that produce a noise of 9-45khz with flashing leds,5 times about every 3 minutes,so I can hear and check if the thing is working always,now I think that no spider or mosquitos will try to approach my car again ;-)
