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

Detector works like it's supposed to. This came with batteries already installed. Nice loud beep. Pretty easy to use.

Easy to use. Had to replace 7 wired smoke detectors where finding the correct circuit breaker to disable electricity can be tricky. After learning smoke alarms dont have dedicated circuit breakers with most tied to bedrooms, this voltage tester helped ease my fears. Works as it should. Showed active hot wires by just holding it inches away without actually having to touch wires. You need this in your tool box.

Works as expected. Good simple tester for the cost. Tested it for a while before using it. Fairly accurate, only acted questionable once when I checked a known off wire but could have been detecting nearby energized wire

Worked like package said

tester is one of those inexpensive tools that is incredibly handy to have around the house. For just $9.99, it gives you a quick way to check for the presence of voltage without having to make direct contact with exposed conductors. I really like the dual-range 12V–1000V / 48V–1000V settings, which make it useful for a variety of electrical troubleshooting and DIY projects. The LCD display is another feature I appreciate because it gives you more information than a simple light or beep. The audible alarm and flashing indicator also make it easy to notice when voltage is detected. The built-in flashlight is a surprisingly useful addition, especially when you’re working inside cabinets, behind appliances, or in other dimly lit areas. It’s compact enough to keep in a toolbox or drawer, and the controls are straightforward enough that it doesn’t take much time to figure out how to use it. I’ve found it especially useful for basic household electrical checks, DIY projects, troubleshooting outlets and switches, and working around electrical fixtures. One important reminder with any non-contact tester: I would use it as a screening tool rather than assuming a negative reading means a circuit is definitely safe. For electrical work, it’s still important to follow proper shutoff and verification procedures. Overall, this is a compact, affordable, feature-packed voltage tester. The dual voltage ranges, LCD display, audible/visual alerts, and built-in flashlight make it an excellent little tool to keep in a home toolbox. ⭐⭐⭐⭐⭐

What a lifesaver! I'd been searching for a 120V line voltage detector for ages, but they were all over $50, and some as much as $160. Then I saw this beauty! Inexpensive! Easy to use! Compact! And again, a lifesaver! I had a large bundle of 120V Romex in the attic space. Unfortunately, determining which one to use was the issue, and there was no way I was going to spend hours and hours cutting little notches in them and test with my multimeter. So the bundle stayed left alone for quite some time. That was until I purchased this gem. I was able to determine the correct line in under 20 minutes! Now theres a 2-gang outlet which now runs the attic fan and LED light! Next was tracing wires in the garage walls. The previous owner had a small shop and added an additional fuse to the panel. He also added an additional run of outlets, but they were at different heights. As a few were up high, I couldn't tell if the wiring ran along the upper area of the wall or back down? I'm glad I had this tester! He did run a few outlet wires along the upper interior wall! If I hadn't checked, I would most certainly have cut them! If you're in need of a user-friendly line voltage tester, this is the one to get! I LOVE this tool!

Being relatively 'fluent' in electronic stuff with most of the right tools, I had limited test tools for the electrical side of things. Tired of hauling out a multimeter for simple power present verifications, I bought this tester. Found it to be just amazing. Easy, simple to use, immediate results when testing AC outlets and even cables, for the presence of power. Not a voltage measurement device (multimeter) however for the quick 'use caution - power is indeed present here' type tests, it is the cats meow! Terrific $10 safety addition to my DIY toolbox. Highly Recommend.

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.

J’ai acheté ce produit parce que je fais des rénovations. Je change les vieilles prises de courant et interrupteurs ainsi que les luminaires qui datent de la construction de la maison. Ce testeur de tension m’aide dans cette tâche. Il est facile d’utilisation et fiable. Les batteries sont incluses. Un bip indique que l’appareil est fonctionnel lorsqu’on appuie sur le bouton power. L’appareil est muni d’un pointeur laser et d’une lampe torche pour les endroits peu éclairés. Un signal sonore et un voyant lumineux rouge indiquent la présence de courant. De plus, la forme de l’embout permet de le rentrer directement dans la prise avant de couper l’électricité et juste après. On n’est jamais trop prudent. Je le recommande.

Excellent quality and good proce

Nice little unit, works as advertised

No regrets

My husband love's it we had to change wires to outside lights and because of that I had to get one.....thank u
