Non-Contact Voltage Tester is rated 4.5 out of 5 by 747.
Rated 5 out of 5 by from It Works I work for a property management company (2000+ units) and this tool has served me well. It makes it easy to determine if the problem with a light fixture is the ballast, lets me know if I'm working with live wires, and just saves a lot of time over uncapping wires and using a voltage meter. I've read other reviews dealing with problems with the power button, but I have not experienced this. I keep it in my tool bag and carry it from job to job constantly. I've dropped it off ladders, leave it in my truck in below freezing temperatures, and have only had to change batteries once after using for almost 6 months. Worth the extra money.

Rated 5 out of 5 by from A must have tool in every toolbox This non-contact voltage tester is very easy to use, highly accurate and durable. I bought it to replace a less expensive model and the difference is amazing. Definitely worth spending the extra money. I mostly use it to make sure the power is off before changing outlets and switches. I also use it to test power cords when something doesn't work. I've saved thousands of dollars by diagnosing that a device isn't working because the power supply or power cord is faulty and simply replaced it rather than buying a whole new product or making an expensive service appointment. I highly recommend using this device and specifically the Klein brand.

My wife and I bought an old house and there were any number of electrical issues that arose almost immediately. Where does this wire go? What switch does this turn on? Is there any power connected to this fixture? You name it. This little device saved me hundreds of dollars in not having to hire an electrician to answer some basic questions. It's non-invasive, simple to use and more than cost effective. I have other electrical testers for outlets and such, but if you need to follow a wire or just come across one that you don't know if it's live or not, this will save you time and maybe your life.

Absolutely flawless, hands down one of the best purchases I've made in a long time.  I can't speak highly enough about this product, which is solidly built and perfectly designed.  It has become a staple of my homeowners tool kit.  I've used it at my house, several friends houses, and my wife's business during electrical renovations across a wide variety of DIY projects.  This unit has helped me run wiring, map circuits, rewire rooms, install sockets and plugs and switches.  It's a constant companion and I love it.  It works peerlessly sounding both an audible and visual alarm when current is detected.  It's so easy to decipher, my wife has used it to help me map the wiring in my new house since the diagram on the panel was completely inaccurate.

Rated 5 out of 5 by from Works as advertised My combo tool,a stripper with a proximity tester started giving me false readings,and became totally useless as a voltage detector. Saw that my regular electrician had this tester and got one for myself. What a difference! Not only does it let me know if the line is live, it can discriminate which side the hot wire is on in the in the cable. A little pricer than some of the others,,but in this case I guess you get what you pay for. This particular old house has circuits running every where,so even throwing the breaker ,,you STILL need to know if the line you have is live or dead,,,had enough surpprises in the past,don't need any more!

Rated 5 out of 5 by from Can't go wrong This was my third similar volt tester. First time with the Klein brand. The other green one I had did not last a year. The Klein tester was a few bucks more than the others. I love it and am glad I was not being cheap. The nicest thing is the tester has a audible warning device. Turn it on and it beeps. Turn it off and it beeps twice. Hit a hot wire and you get a steady tone. I have been bit by a hot wire before because the battery had run out in the old tester. This is no longer an issue. As long as you get the beep when turning it on, you can count on being safe.

Rated 5 out of 5 by from Great for DIY projects I bought this tool to help with wiring my basement. It is also good for helping trace wires that are in bundles coming out or going into your breaker box. a must have product for any home. A green light will tell you that the pen is on and working. a red blinking light with alarm will tell you the line is hot/active.

Rated 5 out of 5 by from As a licensed electrician with almost 45 years of experience?... As a licensed electrician with almost 45 years of experience? I never leave for s job without this in my front pocket. Never presume a circuit is off unless you personally have tested it. Never take another persons word that the circuit is off. Most electrical accidents could be prevented if people would adhere to the 3 very simple rules of electrical work; 1) test the circuit to be sure it's turned off. 2) test the circuit to be sure it's turned off. 3) test the circuit to be sure it's turned off. When in doubt refer back to anyone of these three rules.
