I love this thing. It has significantly reduced the mosquito population in my back yard. I don't think it covers an entire 1.5 acres but it works pretty good. I live on an acre and I will buy a second one to cover my property more completely. I read a lot of reviews from people complaining about the noise. I love to hear it, it sounds like the sweet sound of revenge to me. The cord is short but you will probably use an extension cord with it anyway, so not a problem
