  • Red is hot green is not
Style: NCVT Pen Pattern Name: Tester
A nice size pen to check voltage in your household wiring. This is easy to use. Put in the battery and press the on button. When you hold the tip next to or on to the wire you are checking, it will either stay green for no current or if the wire is hot, turn red and buzz. This is a must have item for around the house when checking your electrical outlets and connections. Stop guessing and go for accuracy. The pen is worth the money and works every time. ... show more

  • Simple to use
Style: NCVT Pen Pattern Name: Tester
Overall, it does the job. I was changing burnt-out Christmas Light bulbs and sometimes it gave me a red light and sometimes it didn't. At first, I thought it was misreading the hot wires, but I figured it was a low voltage running through the wires therefore it was giving me a false positive reading. I ended up changing all the bulbs and now the wire all reads hot. ... show more

  • Contactless, Speedy, and Mostly Idiot Proof!
Style: NCVT Pen Pattern Name: Tester
This is my third Klein Tools non-contact voltage tester and they are excellent. This little tool is invaluable for anyone that touches those things electrical. I’ve certainly kept myself from receiving a nasty jolt on more than one occasion, so whether you are changing out a light fixture or working on a malfunctioning lamp, this tool is an invaluable helper. It’s no wonder that I keep giving them away to my friends to help keep them safe in their electrical endeavors. ... show more

  • "Old reliable" and a great gift for the DIYers
Style: NCVT Pen Pattern Name: Tester
I'm a retired contractor and I have used these testers for 30 years. Great to keep in the pocket or tool belt. I've given away, probably, 10 of these to my customers over the years. Very handy and safe to use.
