[This review was collected as part of a promotion.] excellent vaue, works great

I wish I had this tool when I was a young Field Service Engineer for Measurex / Honeywell. It is superb at finding faulty or non-existent grounding on electrical equipment. Some folks may complain it is too sensitive, detecting AC fields on UN-plugged equipment. I prefer this sensitivity over all other products since it can find stray fields where other testers fail. The Laser Distance Meter is very accurate and makes for an all-round versatile tool.

the tester is good and reliable but the laser is completely inaccurate it doesn't know the difference between 30 inches and 30 feet.

Decided I needed to invest in a reliable Klein Non Contact Voltage Tester after epic fails from 2 Non Klein testers, Im NOT GOING BACK!!
