Title: Does the job.
Review: I live in a 48 year old house with absolutely terrible wiring. Stereo systems, computers, and the flat panel TV using these line conditioners have all continued to work flawlessly. I've had multiple electronics failures where I haven't used it.It does make an audible clicking noise when the line voltages drop or surge. The sound makes me feel warm, fuzzy, and protected.
