KAIWEETS Voltage Tester: Non-Contact And Contact Pen For 12V-300V NCV Testing, LCD Display, Live/Null Wire Detection, Buzzer Alarm, And Wire Breakpoint Finder - VT500 Review

I purchased this for a specific purpose. Allows me to tell if there is current in a wire before working on outlet etc.I tested it on both 110V and also on my ipad charging cable. simply touch it to the outside of the cable and it beeps if there is current. In heavier shielded wire (power cord to compter monitor it does not register so have to test closer to the plug.If your doing electrical work, this is a must have so you do not touch/cut "hot wires"

I like the sensitivity of the tester when looking for A/C using induction. I also like that it has a bare metal tip so you can test for live A/C by touching the wire. I won't be trying out the continuity test, sorry!This tester is considerably better than my other plastic tipped tester that is not nearly as sensitive and can't test exposed wires directly to see if they are live.

Likes:It uses a standard AAA battery rather than a hard-to-find button battery like my old tester.It has beeps plus has a digital readout of the voltage. My old one just beeped.The screen glows green for low voltage and red for high voltage.This has a LED flashlight, although not real bright its more than my old tester had.You can use this to test the polarity of a battery. It's a plus but I don't see the need to do that too often.This also has a continuity tester. You have to actually touch…

My last non contact works but is limited after a drop. There's no adjustments in sensitivity to make this "work" or not. I'm not going to write on if it's precise because my skill set is limited, I intend to use this with household simple fixes investigation. Nothing very sophisticated or high end electronic repair. If my savvy inlaws borrow, it I may update then. For the extra features, it includes instructions on how. If your skill level can't discern them and feel confident, don't use these…

I already had one of these that seems to work but it's adjustable and I don't always feel I can 100% rely on it. So I thought I'd try two more and this one I liked because of the digital readout, which seemed an extra bonus.I may be missing something but this seems to have low sensitivity when trying to detect voltage. When holding it near an outlet, for instance, this thing is silent until you place the probe right on the slot for for "hot" -- the narrower slot. Otherwise, nothing. If I…

I need a tester that is a no contact that I can use without undoing my low voltage lighting in the yard. To say this works as it should that would be a lie does it work in a perfect area where all is good yes, but that is not the case if you have this unit in your hand wondering around your yard. So, it seems I will be sending this back and once again start looking for a reader that does what the manufactures clime it does.

When Halloween came around this year we hooked up our inflatables and . promptly burned out our only exterior outlet. Never had that problem before, but we worked around it by running an extra long cord to the electrified shed . and burned that outlet out too. This was a much bigger problem, because the shed charges my other tools and it meant I effectively couldn't use any of them.It turns out that the original outlet was on the same circuit as the shed, but we didn't know that and couldn't…

For the price it is a good tool to have. There are some short comings that come with it though. I have a hard time making the display warn me that I am touching a hot connection on newer type outlets. The rather large metal tip won't let you in deep enough, but older outlets do. I tested it with another higher end tester and even though its metal tip is encased in plastic it is thin enough to read that you have a hot wire in the newer outlet. The LED light is not as robust as the more expensive

I got this voltage tester just to use as a quick and easy tool to check whether a wire is live, without needing to contact the metal or deal with multiple probe connectors like a digital multimeter has. I have a non-working ceiling fan to replace and this seems well worth the money for the added safety check before I start touching the wires. It works perfectly for that with AC-powered wires. When I put the probe against any insulated wire in my house plugged into an outlet, the device beeps…

This works great and is perfect for a Do-it-yourselfer like me. I'm adding some additional outlets in my garage and also remodeling a bathroom, so this is coming in handy for my rewiring.Small and compact but yet works great and is accurate when reading the voltage.I like that it has a buzzer alerting me to an energized circuit. I find myself using this feature quite often and makes for quick checking of the wiring.The continuity part of this works great as well even though this isn't something

I was a little leery when I ordered this. A one probe voltage tester just sounds wrong. I have been building electronic equipment and wiring higher voltage for many years, up to 480 volt irrigation plants out on the farm. So I was a little surprised when I opened the box and found a tool that looks to be well made and actually does most of what they claim it will do. With one lead it really does tell which wire is the hot one on AC. It does estimate the voltage and if all you need is to know…

A solid NCV. The display was easily visible and I liked the auto turn-off. It was getting different readings than my Fluke meter, but I got this just to have handy to check for live outlets. Of course, this device will confirm that an outlet is "live," but I never 100% trust a NCV to tell me a circuit is "dead."Not sure what the value of a battery polarity checker is.that should be pretty obvious for most batteries.Likewise the "screwdriver." It looks like one good twist and that…

Kaiweets really makes some advanced tools, and yet, is at the low end of the price spectrum.this tester works as advertised and is quite interesting.as a HOT tester, it works well. and determines differences in voltage by the closeness of the beepsit also tests for continuity, by using your body as a conductor, grab one wire, put probe on the other, it works remarkably well, which makes sense as your body is nearly all water, a good conductor. just be sure the line is dead first! ;) It also…

I find this pretty useful. Mostly because it had a readout vs just an audible alert. I’m still learning how to use this but it appears to be more capable than the basis beeping indicators. That’s appreciated!Oh, and I also love that I can be sure its "off”, where was the ones that turn off on their own have always bothered me since I can’t confirm they’re off.

Useless device and dangerous. Holding the device in my hand, plastic only, got shocked wherever I tested with it. The buzzer alarm is not loud enough to be heard in noisy environments!

I recently put in two closet lights and realized I should REALLY have a voltage tester. This unit was a good value and it works great. It makes electrical jobs so much easier because you don't have to wire things up trial and error. I'm pleased to have this. It will make the electrical things I do around the house safer. No one wants to zap themselves putting in a light fixture.

While is nice hotstick, is OK for testing circuits, but rather a not recommended for individuals that is not experienced or have knowledge with electricity.

This voltage tester is lightweight and compact. When voltage is detected, the sound it makes is not too loud. Also, it is convenient to use as a screwdriver. The display is bright enough to see information in the dark. I have nothing negative to say about it.

This voltage Tester is nicely designed works well small compact fits in your pocket or tool bag.So far I'm pleased with it.

I replaced a few outlets and I got this tester to help make sure the wires were not hot anymore before I open and replace them. This tester worked as advertised and I was able to safely replace my outlets.
