      Parasitic Draw Tester

      Posted by Benjamin P. on Dec 27th 2017

      This parasitic draw tester is one of the greatest testers that I have ever owned. Finding the issue when using this is never a long struggle and it is always correct. I have before had testers that have given us the wrong diagnosis and for this one to be so great is such a relief. The price really is not a bad one to pay considering how great it is.
