      Overall: 5 out of 5

      Anyone who works around household AC voltage needs one of these. It works great to test for any live (aka dangerous) circuits.

      Overall: 3 out of 5

      Has all the features I wanted. Quality up there with 'Fluke" but at 1/3rd the price

    • "Works as advertised" by paulmoffat on 5/3/2012
      Overall: 4 out of 5

      Good value, documents could have been clearer as how to install batteries, and turn it on and off (hold the button down for 2 seconds to turn off).
