I am about 10 years in possession of the Power Probe has been always very well rendered services. Unfortunately, at some point could no longer mass are switched, it was needed as a replacement. When searching I came across this LED Tester. It fulfills the same characteristics as the Power Probe is processed very valuable and has in the first testing and troubleshooting both in the continuity testing as well as in stress testing his job done just as you would expect from him. What really amazed me was the extremely low price compared to the "original". I could not determine what the additional cost justifies far. I will in due course announce whether the durability can compete with the Power Probe ...
