Summary: I may not have spent as much on this set had I been able to try it first. I have seen many technicians do well with much less expensive toners and probes. Great marketing job on FLUKE'S part.

Summary: This tool has been indispensible in our organization. I routinely have to trace cat5 cables from jack back to a wire bundle at the patch panel. Before I got this tool, I had to carry a probe set and a wire tester. My only complaint is it was a little pricy.
