Title: Simple Does Not Work
Review: I bought 6 units (WHI-3C). Manual says "Clearly TRANSMITS pure, static free, two way voice". But once it goes through your power lines you will RECEIVE a lot of STATIC. I tried all combinations on both legs of circuits. Won't work through UPS or GFI or on opposite 120vac legs of the house supply. Advertising is very deceptive. I am going to be hit with a 15% restocking fee. Tech support is only for contractors.
