I've already used this half a dozen times since purchasing it not too long ago. These simple accessories greatly expand the capability of the Klien ET300 (and similar devices). Using this (and the ET300) I was able to diagnose a GFCI failure and find several circuits in my home that didn't have outlets. I would have been out of luck without it.
