VENLAB 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

Works as advertised. Nice price

This unit was opened 5 months after purchase and would not turn on even though batteries test good. I don't know whether this is a one unit defect or a recurring problem. Update: Operator error, The unit is working normally. It is sensitive and easy to use.

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.

Works like it should but seem bigger than others I have used.

Gracias Hoy cuento con una gran herramienta que me va ayudar a salir adelante gracias a Dios Thank you so much for this great tool, but first I thank God because it's in my hands. Blessings.

simple to use, very helpful.

Excellent choice. Gets the job done easily

It's cheap. Works. But not as good as others.

Excellent quality and good proce

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.

Nice little unit, works as advertised

No regrets
