I bought this Pest Reject device online on konga.com. I tried it for a while and didn't notice any difference with mosquitoes. The device later stopped working. The red light wasn't showing again. So I opened it up to check. I was shocked to see the inside. It only had a diode, resistor and an LED red bulb. There was no other component to generate Ultrasonic sound as claimed. This device is fake and a scam.
