Made replacing all switches, outlets easy!

I have wanted one for a long time. The cost is now affordable and the features are much more useful than the old neon glow lamps ones from my youth. This little gadget has helped to replace old light switches and plugs by easily finding the "hot" wire, ground and low side of my wires. The wires are so old they did not come with colors or tags. I even found one connection upstairs that turned out to be "hot" all the time due to a short.
