  • 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

  • Sweet tool
Style: NCVT Pen Pattern Name: Tester
Really neat tool. You can tell if you have power in your cord by just touching it. It will tell you which side of the cord is hot. Very handy, and it works

  • It works
Style: NCVT Kit Pattern Name: Tester
Unit works fine, but there were no batteries included with mine. Ad and packaging stated that batteries are included. Oh, well, I keep batteries on hand so not a huge deal.

  • Reliable
Style: NCVT Pen Pattern Name: Tester
When you are about to grab electrical wires I want a product to tell me reliably there is no voltage. I’m an electrician and this is what I choose. It’s quick, easy to use, and fits in my shirt pocket so I always have it. It has a mode that shows red with voltage with or without beeping. Klein products are union friendly as well. Worth the money and piece of mind. ... show more

  • Works great
Style: NCVT Pen Pattern Name: Tester
I paid more for this name brand instead of a Chinese knockoff. This worked as advertised and detected the hot wire I was looking for when I put the batteries in and used it on day one. It seems like it’s well built. I’m glad I bought this.
