Extech Instruments 40180 Tone Generator and Amplifier Probe Kit

So I bought this to trace a faulty lead back to my ECU, The product looks very robust in the picture but turned out to be regular flimsy plastic. Getting the battery in the probe was a particular nightmare as the fitting is too tight and the leads too short and not having the dexterity of a concert pianist or surgeon I was lucky not to brake the thing before even using it. I followed what little instructions there are but after an hours worth of trying could not get the thing to trace a cable, it just kept ringing wherever it happened to be pointing, you could point this thing at a bucket of blancmange an it would ring indicating a cable. What really annoyed me was that I thought I'd purchased one of the better quality ones but the lesson here is that, just because it's yellow does not mean Dewalt quality. I don't know if I can send it back as I've tried using it but it certainly didn't do what it said on the tin.

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.

GOOD tool!! remember: turn off power to the line youre testiong: extraneous noise can confuse your interpretation.. tkjtkj, mech.eng., m.d. ******************* My criteria: 5-star: does the job well, with extra advantages 4-star: does the job well 3-star: helpful but doesn't accommodate all needs that one would expect 2-star: sketchy performance at best 1-star: Fails in significant ways ; but they showed up for evaluation 0-star: Where are they hiding???
