Someone installed grounded outlets on ungrounded wires in our 1960's house. This device helped us identify affected outlets. Most things in the house were ungrounded. We also found some wrong reasons and reversed polarity. From what we found, licensed electricians grounded all outlets, lights, and switches. It was an expensive project so we used it to test their work in retail stores which was an added convenience for us as consumers. I recommend this for consumers with old houses!
