Non-Contact Voltage Tester Tools,LED Flashlight,Buzzer Alarm,AC Voltage Detector Pen,Test Range 60V - 1000V for Live/Null Wire Judgment

Good price and works like it should!

I purchased this item to replace an identical tester I had for several years that had finally failed. This is such a great tool to have for safety if you plan on working with electrical items in your home. The last tester I had failed from the batteries leaking when stored and ruining the electronics inside. I dont plan to store my new unit with the batteries installed like my last tester for obvious reasons. This replacement tester is as equally effective as my last and I won't work on electrical projects without it. I've changed several ceiling fans, outlets, and light switches within my home. Sure its relstively easy to tell if a breaker is off by other means but don't you want to know for sure? A back up way to know your not going to get electrocuted? Not only can you plug this into the hot side of an outlet but you can just touch hot wires with the tip to see if there is power. You get an audible beep and an internal visual led that lights up the entire front casing red when a wire is hot. There is also a while led "flashlight" option which comes in handy when you kill the breaker and have no light in a particular area. It responds very quickly with no real delay when it touches power. I would say it is very sensitive and very accurate. The size is great, it can fit in your pocket or easily be stored in your electrical work box or case. But it's not so small that it's easy to misplace or lose. For the price it is a great piece of mind. I highly recommend this tester!

I bought this when I started to replace the electrical outlets in our home to newer versions with USB A and C charging ports. Because I needed to correlate the various outlets to the right breakers, this tool came in handy to help make certain the power was turned off. It worked fine and is easy to use.

works well

I bought this as a Christmas present for my 10 year old great-nephew. You know who his father is?My nephew. You know who was a little pain and annoyed me when he was a kid? Yep, that nephew. The lad loved this thing. I showed it to him and he ran around my sister's house, the lad's grandma, holding it up to the light switches and wall sockets and it was going, Beep-beep-beep, half the night. I showed him how it worked on many of the walls that had wires in them. Now that is educational for a kid to learn. My nephew sneered,"That's a nice present", sarcastically. I told him it was his karma and payback. He owns a bakery and I mentioned that he could probably borrow it and use it there now and then. He admitted that, yes, he could, more often than he liked. More creative than a drumset. Get one for your grandchild, nephew, or you friend's kid. Their parents will thank you. Very affordable.

It lights when you press the button with or without a power source! So there is no way to tell whether it detects any power or not. Also opening the battery compartment is practically impossible. Cheap, useless crap.

Tester works however it is way too sensitive to be usefull. Starts beeping when I place it over 6” away from hot wires. Cannot tell which wire is the hot you’re looking for. Identifies any close wire as hot. Works fine on a single wire or single outlet just not good for a bundle of wires.

Excellent, it's what i expected

Funciona pero da falsos positivos y es muy general no sería capaz de seleccionar el cable energizado de entre varias opciones si los tienes todos en la mano. Por otro lado es bastante más economico que las versiones más precisas. Lo deje para cuando es solo comprobar si algo está energizado a groso modo para el trabajo fino sigo con el fluke

Comodissima fa il suo lavoro,La consiglio

Conforme à l annonce, très facile d utilisation, fonctionne parfaitement. Piles non fournies.

Non molto affidabile suona spesso senza motivo non è preciso per chi ci lavoro.

Demasiado sensible, cuando quieres ver varias fases si tienen tensión no sabes cuál tiene y cuál no tiene.
