5Extech 40180 Review
By Scott Franson
Worked like it was supposed to. We used it to trace out speaker wiring in a house so we knew where to cut our holes for the speakers. We also use it when we run CAT5/6 in office buildings to trace the cable from the outlet back to the switch or punch down. The only slight problem we had was when we would trace the speaker wire. I guess the signal was strong and we would get some induction on the other wire that we were not tracing. But we didn't miss a hole or cut in the wrong spot, the wire was there.

5Works Well
By Charles G.
This thing works well for its intended purpose and is of high quality. To one of the earlier posters, it isn't *supposed* to find wiring behind wall board, it is intended to locate wires on a punch down block or other available source. And for that job, it works perfectly. Highest recommendation.

5As good as it gets
By Archangel
I have been using this "toner" kit for more than a year now on a nearly daily basis and it works very well. I use it in an industrial environment for identifying circuit wiring for things such as street and area lighting, motor wiring, instrumentation wiring and the like. It is one of the most used and most useful items in my tool collection and has proven to be very durable and reliable over this entire time. This is a great product for what is was designed to do.
