Cheap Life InsuranceThese things are life savers. 16 bucks is a cheap life insurance policy when working with high voltage. These can be used for really basic troubleshooting as well, but I mainly use it to verify that the power is OFF on circuits that need work performed. Nothing will take place of a volt meter to verify that circuits are safe to touch, but this tool a great secondary check, just to be sure. I had one just like this, but it fell off a scissor lift and bounced on the concrete 20 feet below me. Pretty sure the warranty won't cover that, so I bought this one as a replacement.5Not impressed at allSays "Non-Contact" but unless the probe is in contact with the metal in the circuit it wont read. My $10 version I picked up at walmart is 100% better1Works Great! Just DON'T drop it!Professional electrician for 42 years. This is the real deal for non-contact voltage detection. My only real complaint, and it is significant, with this tool is the switch. The on-off switch is its weakest point. There are two types of switches on these devices. The one with the switch near the testing end is pretty reliable. The one with the switch at the end where the batteries are installed is a REAL problem. I have purchased 5 or 6 of the ones with the switch at the battery end, and frequently need to take them apart to "tweak" the switch. It seems the switch easily becomes misaligned and either the button doesn't contact the internal switch or the electrical connection is compromised. VERY annoying! I have learned that I'd better have at least 3 of these available at all times. If they fall from your pocket onto a hard floor you will likely find it's time to "tweak". After a few tweaks, you may not be able to get it to return to operational status. This is the reason for 3-star rating. (Wish they had 1/2 stars. It really deserves 3.5 stars) If they would warrantee the models with the stupid read end switch, it definitely would be FIVE STARS!As for accuracy, these are GREAT! When you get close to an energized wire they beep and the light changes color. When you need to know what wire is what, these are a valuable tool. My only complaint with the accuracy is that in a multi-wire circuit, (like a 3-way circuit) it is somewhat too sensitive, making it difficult to isolate the actual HOT wire from any other ungrounded, but actually NOT energized conductors. It is a minor issue, and certainly does not make the tool unusable.If you get one with the switch near the front you're good to go. If they send you one with the switch on the battery end, do yourself a BIG favor and return it. And remember. DON'T drop 'em!3Accurate and Dependable.I have used this little Non-Contact Voltage Tester "Stupid Stick"(Trade Lingo) for the last month. In a box filled with wires it will locate the hot wire no problem. Not all stupid sticks are built the same. In the past I have had some cheap ones that beep within 12 inches of the hot wire, and would pick up static from wires that ran along side the circuit you are trying to determine is live or not. they really did not work very well. This one works great and I'm not one to bet my life on any electronic device but this one comes close to me betting my life on it. I give it a 5 star for Accuracy and Dependability!5Functional but not the best design.The alert chirp was not loud enough to be easily heard in a noisy environment. The red LED was on the back side and not easily visible if you are right handed and checking wires at eye level. A better design would put a green LED ring around the barrel about inch back from the tip and a red LED ring around the barrel between the green ring and the tip. Both rings should be neutral opaque until lit. Chirp should be much louder and get faster as it approaches the hot wire. Now it won't even chirp if the insulation is thick on the wire.3Every DIYer Should Have OneI am a finish carpenter, and my renovations often include minor electrical work. I have had one of these Klein testers for many years. I bought this one for my son, after he told me of a minor home renovation project he had attempted. No one should attempt working on or around electricity without one of these. You just touch near any wire or switch (you don't even have to touch it), and it tells you whether there is ANY current running through. It could save your life. .5Garbage -- continually provides false positive readings. Useless.In a word this product is garbage and is being sent back immediately to Amazon. I also bought the Fluke product thinking that I'd keep both if both worked OK. The Klein product continually went off (indicating live wire) when romex was dead. Yea, the Klein has 100% sensitivity and 0% specificity to put it in technical terms. Just manipulating the device would cause it to go off. The Fluke on the other hand has been 100% accurate (no false positives and no false negatives). The Fluke product is twice the price of the Klein but obviously worth it. The Fluke is so good that it will tell you which side of the romex is live and which is dead (i.e., the line side and the load side of the romex). This one is a no brainer, pass on the Klein and get the Fluke.1Klein Its temper mental sometimes, false reading while holding it upside down or the on/off switch won't work. Usually removing the batteries will correct it. I've used Fluke and Milwaukee, and they can be equally annoying. I bought this one "used" but there no indication it had even been opened. 4Inconsistent, cannot trust that it's working...Unpredictable, works sometimes, sometimes not. Won't detect voltage in a live outlet. False alarms on conductors with an open breaker. Sometimes it beeps when turning it on, other times it doesn't. Turning it off is also inconsistent, sometimes it turns off with a slight touch of the button other times it won't shut down unless the button is held for several seconds. Not the tool I want to use before I touch something that could still be energized. Cannot trust this thing. Returning it.1Stopped working - very dangerousI had this product for a few months and it stopped working. It always shows green even when touching a hot wire. I hired an electrician to change an outlet and showed him the tester - he verified that it's not working. Changed batteries and still not working. Very dangerous to use a product like this. I contacted Klein and their return process is not convenient and not even guaranteed. I have heard good things about the Milwaukee tester so I will try that one.1Good for homeowners and handymen.I manage a property and this lives on my hipbelt.Mostly use to double check power is off when working near electrical (outlets, wall heaters, etc), but also handy for some troubleshooting. Before relabeling all the fuses on the property, this did save me from a potential shock.The lights and audible alarm are both nice, but I usually just use the light.Can be a bit finicky though. Will sometimes flash red when just tapped against something.Always check on known power source as they recommend.Also wish button was more low profile as it will sometimes be turned on accidentally. Suspect that's why auto shutoff is a feature.Overall it's worth the money for a trusted brand and a little peace of mind.4Seems professional grade to me For years I've used the Greenlee version of this tool. It has always been a useful tool. Then, I wanted to use that and saw the switch end cap was missing, and no luck finding it. That end cap was always the weakness of the unit, it came off too easily while turning it for on or off.Thus I decided on this Klein unit. Wow, a world of difference between this and the Greenlee with this one significantly better. It feels solid, the indicator lights are brighter, the power button is great, nothing to dislike about this unit. Highly recommend this one over the Greenlee. Now that I bought this one, I'll likely find the missing Greenlee end cap, you know how that goes, but this Klein unit will be the one i will use from now on. 5I love one-handed testing! This Tester works very well and I have used it to trace a problem in my shop lights and to diagnose some Christmas Tree lights. Being able to test lines with one hand is extremely helpful when you are standing on top of a ladder and need one hand to steady yourself. Quality of the product seems to be very good and having now used it at least a dozen times it has not failed me once. I highly recommend this product for the DIY'er!!! 5A reliable, accurate, non contact voltage tester at a reasonable price. Very easy to use and accurate voltage tester. This won't take the place of a good multimeter, but what is does it does good. First off what it doesnt do: it doesnt measure voltages, amperage, ohms, capacitance, and/or frequency. If that's what you need, you need a good multi meter. What it does: It let's you know if the circuit is live, and if its safe to touch. I use mine in conjuncion with my multimeter. I wish the pocket clip were a little stronger and more robust, but for the price, one cant go wrong with this product. I love the multi colored light led that visually warns as well as the audible alarm feature. I wish the audible alarm were a bit louder, because in a loud, industial, environment, one has to listen closely and look at the visual alarm, but like i said this is one of the best non contact voltage pocket pens available, so buy with confidence, knowing that if used correctly, one can diagnose live circuits safely and with ease, and when its time to repair you can assure that the electricity demons wont bite you. 4
