Works Very Well

 Would Recommend

I have a break in the line for my hall closet light, so I cut the wire and moved the fixture. I was able to find the break in the line by using this non-contact voltage pen. It lights up nicely when electricity is present and provides light to see the line I am working on.

Good Tester, Does what it is intended for.

 Would Recommend

Tester does great and is a must for homeowners that do DIY electrical projects. This makes sure the wife really shut off the power not just wanting to claim life insurance. hahaha

A basic tester

A basic voltage tester that does what it needs to do, beep and light up! I'm using it just to detect if there's voltage at all, with no more information needed.
