Neoteck Voltage Tester/Non Contact Voltage Tester 12-1000V/48-1000V Adjustable Sensitivity AC Voltage Detector Tester Pen Live/Null Wire Tester With LCD Display Buzzer Alarm Wire Breakpoint Finder Review

Bought the one with the sensitivity switch because so many complained it's too sensitive. With the sensitivity switch on, it detects voltage in the wire whether the fence is plugged in or not. With the sensitivity off it works perfectly. So much better than my old two prong wired light I can only use at night because I can barely see it: this lights up well and also beebs for me too.

I got this tool after reading some reviews about how it was used to diagnose someone's Christmas deco lights. Yes, it worked for me as well. Before I had this tool, it was very tedious to find where some lights on a Christmas wreath failed. With this tool, you connect the wire, and it would beep till you encounter a bad light, and then you just replace that light, and so on. It can be useful for other non-contact check of electricity circuit too.

This device is not as accurate as I hoped it would be in determining the common or hot wires. If it is even close to any other disconnected wires, it may also flash and beep as if it were the "hot" one. Otherwise, it is as described and when it does work, the flashing light and beeping sound are quite clear. The small flashlight on the tip is also handy when lighting at the box is lacking.

It’s ok. It’s certainly cheap feeling but you get what you pay for. It works but it was also reading electric currents where there are none so I am hesitant to trust this. I have a different named brand one that is going strong for years but is much more expensive. I guess it’s my fault for going cheaper. Bottom line: will it work, yes. It comes with batteries so that is good, but I can’t say how accurate it will be.

I'm an electrician and my Fluke tester took a crap so I figured instead of paying $28 for a new one I would check this one out. I work around 480/277 volts all day long and this little tester is working great! It also has an LED light on the front of it which has come in handy as well! For less than half the price of the Fluke you can't go wrong.

Glad I added this to my toolbox, but I'll still make sure circuit breakers are off before touching any AC voltage. Didn't work as well as I had hoped for troubleshooting Xmas light fixtures.

It doesn't signal 12 volt current in my landscape wires even though my multi meter shows me the voltage. In some cases, I see a little under 12, which I can understand. In others 12 or a little more and still no signal. Maybe I'll find the tester I lost one day.

Satisfied with my purchase, it works great. Easy to use and I don't know why I waited so long to buy this type of electrical tester. Definitely recommend.

I originally bought this to troubleshoot Christmas tree lights, for which it does not work well. When it is brought near a strand of light it sounds off and lights up. You can not analyze just one light. It is too sensitive.What it does well; if you want to know if an outlet has power just touch the outside of an AC outlet. It can tell the difference between the hot and neutral. Light and sounds on the hot, no reaction on the neutral.I also bought the Fluke 1AC-A1-II, 90-1000V VoltAlert…

I had a GB circuit tester for years before it finally crapped out. I got this Neoteck tester because it was cheap and it seemed to be the same kind of device.Pros: (1) includes little flashlight, that's convenient for working in tight spots. (2) It uses AAA batteries instead of button cells. (3) Easy to use.Cons: (1) It's not as sensitive as my GB tester was -- you can put the little plastic tip right into the neutral slot of a live 120-V receptacle and this unit will NOT beep. I found that…

I started getting more into home improvements and this thing helps! Of course, it's not high quality like you might need it to be if you were a professional. But it's great for doing things around the house. Loud beep too!Done two electrical projects so far and even though I switch the circuit breaker off, it's always nice to know there is no electricity flowing in the wires by using this to check them out. Can't be too safe when it comes to electricity.

Right out of the box you get 2 AAA batteries included (this is huge), you get a quick reference guide, and the Voltage Pen. Pretty straight forward stuff. Works exactly how you expect it, the light is a pretty cool feature since you will be cutting power to certain areas and having a light to maneuver your way through the dark when checking if a receptacle is HOT or not. Overall this is a WIN WIN. Highly recommend this to anyone, Safety First. Worth every penny folks!

one of the must have item if you work on electrical work.it detect hot wires good, but sometimes it also beeps when you bump this devices, so be alert!

Simple and inexpensive. I used this for home electrical work such as rewiring a bathroom, adding a GFCI and replacing switches and outlets. I already knew the basic circuit breaker blueprint, but I have become tired of being electrocuted when either what I am told or what I assumed is wrong. This Neoteck tool helped me determine that I was working with two circuits and not one, thus protecting me from a possible shock. It also helped me determine that the previous owner wired a switch that I…

Overall very happy with this. This is a must have for anyone doing electrical work. Would be good if when turning the spotlight on, would also turn the device on. Sometimes I think it's on but only the spotlight is on. Not a big deal but I have to check every time I use it. The power button lights up when on so just something I have to get used to.

Quickly determine if voltage is present. Bought for troubleshooting Christmas lights . but finding myself reaching for it more and more.

Especially nice that it uses AAA batteries and I like having an on off button and light. I replaced an old craftsman voltage tester that quit working and this works great as a replacement.

The Neoteck non-contact voltage detector is a must-have device and a great value. I downgraded it only because it failed to turn on the second time I tried to us it. No power. Replaced the batteries that came with the unit - no response. I reinserted the original batteries and device has worked ever since. The switch seems okay. I am happy with the unit - just troubled that it might suddenly fail again without a known cause.

This voltage detector is really nice, unlike the rest of them I have. It has a light that makes it easier to use. There is also a LED guage on it so you can see kinda how much voltage and my favorite feature, there is a on off switch so you don't have to hold the clip down for it to work. Also the unit and the LED light all have a auto shutoff.

It is important to know! When you are messing with electrical wire, plugs, etc this little gadget is Very Important cause it checks HOT wires for you, I come from the old school whereas a handyman you think you can do just about anything with no knowledge of what you or trying to do, I have been close to getting shocked and I am 79 years old, so be "SAFE NOT SORRY"!
