5/5

After installing two X25 filterswere installed in my living rooms wall sockets, the eletrical noise in the visible wiring and especially in my computer decreased notably. The noise also became more "coherent" with less spikes. I used an analog am/fm radio for detetcting the noise. Immediately after installing, I have also felt my muscles and internal feeling got notably more relaxed and anxiety decreased clearly. Installation process was very simple. Im happy, and ordering more of these. Visa
