Style Name: Non-Contact Voltage Tester with Flashlight
For all those reviewers that are complaining that this unit does not insert into an outlet, think this through....

I have owned several NCVT's through the years, including the Fluke that has been mentioned, and the older Klein NCVT-1. Yes, these older testers insert into OLDER outlets, and give a voltage detection when inserted all the way in. But, these older testers do not work in the newer Tamper Resistant outlets. Since the Tamper Resistant outlets stop little kids from sticking something in the outlet, they also stop you from sticking in your NCVT. My other NCVT's WILL NOT DETECT on these new outlets, but this Klein NCVT-3 will. This NCVT-3 will now give the same reading on old outlets, or the new Tamper Resistant ones.

That is just one of the things that is great about the voltage scale on this tester. Read reviews on other testers, for any brand. You will see some users complain other units are too sensitive, and then someone else will complain that it is not sensitive enough. Klein stops that with this bargraph. Now, you see the strength of the voltage, and not just a single LED.

I've been doing Electrical work now for 26 years , and Klien has for the most part been my Choice for hand tools.... This tool however is the worst product in my opinion... I've gone through 6 of them already over the past 2 1/2 years , each time getting it replaced at Home Depot where I originally bought it... do not waste your money on this particular Klien tool ... like others have noted , it just stops working for no reason at all,,, and I am one who takes care of his tools... If you have to have a non contact tester,,stick with Fluke...
I'm Even sorry I had to give 1 star ... 0 is more deserving.... C'mon Klien ..

As an electrical contractor I can say Do Not waste your money. I didn't learn my lesson the first time. The second one
had the same symptoms. Works great for a while then gives out. I've tried different types of batteries and it takes
forever to turn ON and then won't turn off. My life depends on it to work.

Style Name: Non-Contact Voltage Tester with Flashlight Verified Purchase
Batteries don't last long, tip doesn't fit in receptacles, if you bump it it shuts off, doesn't give consistent readings so it's hard to trust it. The built in flashlight is why I bought it but I think I'll go back to a Fluke like I had before.
Update: It failed on me, lights were working but it wouldn't detect voltage on known live circuits. Was working on a 277 volt lighting circuit at a University and got a surprise, luckily I wasn't hurt. Most testers fail safe, meaning they indicate voltage on dead wires never the other way around, not this one.

Bought this at Home Depot. Beeps whenever you touch anything.
IE, your skin, countertop, shoe, etc. Not worth even trying.
It's cheaply made with inferior parts. Waste of time and money.

Style Name: Non-Contact Voltage Tester with Flashlight Verified Purchase
Was excited to put the new voltage tester in use on the job. The flashlight was a nice touch, however first real disappointment was the tip will not enter a duplex receptical, so from the outside you cannot definitely know if you have 120v. What you get is the low voltage bars (2) along with the tone. On the neutral side you get 1 bar. Unless you pull the cover, you cannot know for sure if you have the full 120v or stray AC, or some type of short. Won't replace my Fluke which enters the duplex slots with full tone if 120v and no tone on neutral side.

Klein has a good reputation among my contractor buddies so when I chose this tester over other brands, I felt good that it would serve me for a long time.

Nope.

I got to use it less than a dozen times and it failed me out in the field when I needed it most. Just quit. I tried new batteries, lengthening the battery spring to gain firmer contact, all to no avail.

Klein, are you reading these reviews? You should and tell your Chinese suppler to step up the quality control before you lose me as a longtime fan of your tools.
