Easy to use and works really well
This device is GREAT. Put the two AAA batteries in (came with it). I also watched the video. Used it today as I needed to replace a basic light switch. Came in VERY handy. I also have been watching my dad use his old two-wand test meter from the 1970s. This is SO MUCH EASIER and it works!!!!!! When the line is hot, the red light goes on and you get a warning noise. If the line is cold the device light remains green. Just told my daughter to buy this for my dad for Christmas.

Professional grade accuracy—don't trust your life to the cheap stuff!
I upgraded to the Klein NCVT1P after my generic tester kept giving me ghost readings. This tool is much more precise; it only alerts when I’m actually near a live wire, rather than just in the general area. The 50V to 1000V range is perfect for home DIY, and the bright green LED gives you peace of mind that the batteries are actually working before you start testing.

Big improvement over my old one
Power switch on my old sensor from a different brand was the clip sliding back and forth. It never worked right, and you couldn’t tell if it was on or off. This one has a power button and lights up green when it’s on, and flashes red when it detects voltage. Audible alert is loud enough for my deaf ears to hear it. Glad I got this one. It fixes all of my complaints about my previous one.

2nd time buying
Like the title says, I’ve bought 2. Main reason is a temporarily lost the first one. lol they work great and are worth the money.

Hey! I'm not dead! So it works.
Used this to check for a circuit in the wall and I'm clearly still alive. That alone speaks for the accuracy of this tool. But no jokes, Klein Tools are quality. They cost more but they have durable, well-built, accurate and do what they are made to do.
