A must have unit for tracing circuits in buildings

I am surprised and pleased with the excellent build quality of this circuit tracer. It is simple to operate, accurate, and is a game changer for sorting out circuits in older homes, wish I had bought one long ago. You also trace ceiling light circuits by stewing in a plug adapter to the light bulb socket. Wal-Mart had the best price I found too.

Works well but poor design on off/on switch

Works well but on/off switch is very sensitive. Barely touching it will turn the device on accidentally. Poor design there, I had to get a case for it.

Great for finding a live circuit.

Plan to use this not only for finding a live circuit, but also for ease to label the fuse box in the basement. No more yelling "is the electric out"? Very helpful.
