Klein Tools NCVT-2 Dual Range Non-Contact Voltage Tester

We have an older house with equally old wiring. This is a great and safe way to check the reliability of the wiring . Takes just a couple of seconds to check

This is great for the price. It's very durable and dummy proof.

Good Klein tool. Does what it' suppose to.

Me my fiance and daughter found out if you put this to a person's skin while they're touching ground it'll stay green but if they quit touching ground it'll flash blue and beep. Great product I use it regularly.

Good product

[This review was collected as part of a promotion.] I've owned quite a few of these and they are my go to when checking if the power is off. I have yet to have an issue with it reading incorrectly saving me from some bad shocks. Unfortunately I can't say how long they last as I tend to lose mine or a coworker “accidentally” takes it and I never see it again. I can say I've had one for about 2 years with no issues before it was misplaced so it is well worth the price.

The method to switch modes is to hold the power button for 3 seconds. The way to turn it on or off is to hold the power button for ~1 second. The issue is that sometimes when you push the button to power off it sometimes doesn't so you're tempted to hold is more firmly i.e. longer but then it just switches modes instead of turning off. Perhaps I'm not used to it yet and I'll get better at it later. #sweepstakes [This review was collected as part of a promotion.]

I utilized this tester to try to detect a break in landscape line. It did not detect current at various places along the line and at the fixture. I had to pull up significant lengths of the cable to find the break, which I then repaired. The voltage of the landscape line coming out of the transformer was 12 volt AC. I would not utilize this tester on landscape line, even though it is rated to detect 12V current. It does not. The tester seems to work fine at higher voltage levels for me, but was not able to detect current at the 12 volt level. The tech specialist for Klein suggested to me that perhaps I was testing DC current, but I was not. It was 12 volt AC.

Hard to work with. Gives high voltage signal on a 5v phone charger cord. Went back to my single signal Fluke. [This review was collected as part of a promotion.]

I'll start off by every other Klein tool I have is great, but this is the exception. As an electrician I need to use a pen tester often when doing rewired and everytime I pull this out of my pocket I need to unscrew the top and then tighten it, it's never the same either have to turn it multiple time to get it working, to get it to turn on. This seem to be a common problem with the 2 other pen testers I've had from Klein and other guys have similar issues. Spend a few dollars more for one that's far better.
