Electronic Pest Repeller

I would have to give this 3 stars. I put 1 in the kitchen, 1 in the living room, 1 ina bedroom, and the other in another bedroom.
I still noticed a couple mosquitos even with these plugged in and on the right setting according to the manual.

So i'm not sure if these really do work or not, but I wanted to give them a chance.

I still have them plugged in, so we shall see. But for that reason, I am giving it 3 stars.
