Voltage Tester, Non Contact Voltage Detector, Circuit Tester Dual Range Voltage Sniffer 12V-1000V/48V-1000V, Live Wire Tester with Alarm and Flashlight, Electrical Tester with LCD Display

Easy to use and priced fairly. It works well and is a good tool for the homeowner who needs to know if the power is ON or OFF. I recommend it.

I like that it looks slick with it's multi tool use. There is a red pointer light on it, which is helpful when you are trying to show someone a location you are talking about to someone, whether it is in a vehicle engine that you can not point to without it, or something located in another room that is occupied and can not enter, but have ability to see from a glass or open door. The only thing I don't like is the option to have the flashlight on with the red pointer on. The flashlight is not that strong to project the ability to see better in daylight where the red pointer shines on, even from a foot away. Of course depending on how much light is available and how much darkness is on the object. In my opinion, the light is not as strong as most flashlights. It is a weak pen light. I appreciate this voltage tester because it is small enough to fit in a pocket, shaped like a pen, and has a pocket clip that fits in long pockets. The length of the tool might be too long for some shirt pockets. The voltage tester works great. I love that it beeps at you indicating if there is power surging through a connection. The on off button is great. I wish the on off switch was a toggle switch for security just in case you accidentally turn it on while it is in the pocket. For instance if you carry or lean on something and it turns on, you wouldn't know unless you took the tool out of the pocket and looked at it. The only way you can tell if the tool is on, if the pocket material allows the small led on-light to show through. If the fabric is too thick and dark colored, you might not know that it is on. Overall, it is a neat little tool. I haven't test how long the battery will last. Assume also that it is not water resistant, so keep it away from the rain, if you have to do work outside in bad weather.

The tester I received is in great shape. Time will tell for how long, but at a price under 10 dollars, buy this one. The sensitivity is right on and the light is on the right end. The batteries are included and are very easy to access. A voltage tester like this one should be in every handy persons tool bag or box. A very small cost for a lot of safety! Buy some for your friends

My name brand tester malfunctioned so had to buy a replacement. This fit the bill and it was cheaper. Like that changing the battery is much more simpler. It works just as well or even better. Would recommend this Voltage tester.

I used it to to make sure I didn't have any hot wires while installing a ceiling fan. It works great with no issues!

This is cheap and easy, and makes electrical repairs much safer. FWIW, I need to use the high-sensitivity setting to get reliable readings.

Sensitive and worked exactly as described. I've had a volt meter for years, but thesis even easier.

A better way to fix strings of lights. A little difficult to learn to use but in the end, better than plugging light bulbs in and out for hours. With some experimentation, you become pretty good with it. Haven't had to try it on walls to find wiring. Good bang for the buck. If you use it only once on a string of lights , worth the money.
