Neoteck Non-Contact AC Voltage Tester Pen, AC 12-1000V, LED Flashlight, Buzzer Alarm for Live/Null Wire Judgment

This is an excellent tester. Function, quality, price, and easy battery replacement with the screw cap design. My old Klein Tool tester is in the trash. More costly, unreliable, and extremely difficult to insert batteries. Need to depress very small tab with small screw driver. JV3

Works as advertised. Signals on hot wire and different signal for neutral. Safety First. Inexpensive,

Don't know about you but, I don't like messing around with live wires. This tool is the way to go, I've got VTOM meters, but you have to get contact probe to wire. Watched the s.son use one recently so, dang! that's slick! Got one for myself and used it today changing breakers in the service box. I bought an inexpensive one for occasional DYI stuff around the house and it works but time will tell on longevity/function issues.

Great convenient circuit tester for everyday use on electrical situations and objects. You can determine quickly whether you have a circuit problem or a wiring problem or a switch or socket problem or a appliance problem whenever you a confronted with ordinary household situation, including battery run objects. A simple diagnostic tool.

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 still have idea what it switches lol.It worked accurately every time I used it. I can be a bit paranoid so I verified each time on a live circuit that it detected 120vAC (the only voltage I have used it for thus far) as well as verifying that there is no voltage on what I am shoving my hand into to dig out wires. It did NOT detect voltage through drywall (nor did I expect it to), but did detect voltage at the wall plates. It does beep when it is bumped, but this is a characteristic of most brands in this price range. The solution is to approach the wire, outlet or area slowly, then wait for a persistent beep for a positive detection of voltage. I also did not think it was overly sensitive. I had to be pretty much on target for the tester to register voltage.I actually liked the light to look into the electrical box trying to trace where the wires I wanted went to.It seems a little cheaply made, but I tend to take care of my tools. However, accidents do and will happen. This would be my only concern is longevity, which I can not attest to since I have not had it that long.I would recommend it to anyone!

Works great

The media could not be loaded. I needed to change a light switch in my room and this was a MUST. I was able to receive it the same day with Prime and it came nicely SEALED and packaged with batteries, which is lovely. The instructions are clear and simple and operating the device is straightforward. The device is extremely lightweight and about 7 inches in length and under an inch in width, so it is easy to hold. The flashlight feature is CLUTCH, especially when replacing a light switch, since the light source is unavailable of course. The detector is pretty sensitive, so it detects electrical currents pretty quickly. I was able to confidently get right to work replacing my light switch, which was wonderfully convenient.If anyone is needing to do any repairs or maintenance at all dealing with electricity, GET THIS PLEASE! It’s extremely important to stay safe!!! Electric shock is a very serious injury! Better to be safe than sorry, get one of these!

It works but doesn't work with rechargeable AAA batteries which is not convenient at all. Today, I tried using it with regular AAAs and it would make a slight sound but wouldn't come on. Not sure if it is the batteries or if the device has stopped working. Any recommendations for one of these that will work with rechareable batteries? Thanks.
