KAIWEETS Voltage Tester/Non-Contact Voltage Tester with Signal Percentage, Dual Range AC 12V/70V-1000V, Live/Null Wire Tester, Electrical Tester with LCD Display, Buzzer Alarm, Wire Breakpoint Finder

This is a great tool for mapping out circuit breakers in the home of business. It's also great to make sure the right breaker is tripped before performing electrical work, (replacing switches, outlets, etc.). Just get close, and it lights up and beeps if there is power present at the device. This is a great time saver and safety tool to keep you from accidentally working on a live circuit when you could swear you tripped the right breaker, (unrelated to the swearing when you find the circuit is still live the hard way). If you do any kind of electrical work as a homeowner, this tool is a must have!

Seems to work and comes with warning not to rely on it entirely. I tend to agree. It would turn on when I put in AB alkaline batteries. Then I tried rechargeable ones and it still would not turn on. I was ready to turn it back when I notice two batteries on the table. Must have fell out unnoticed. I put in the non-alkaline batteries (no less) and it turned on instantly even though the manufacturer says to use alkaline batteries which did not work. I then took out the plain mercury batteries and reinstalled the AB alkaline and it turns on and seems to work. Jiggle around the sensor to make sure it captures the loose AC radiation and so far it works in capturing them showing the wire or connection is HOT.

The digital readout is the main reason that I chose this no contact voltage tester. But even though it tis the only one that I have seen that has a digital readout, I'm afraid that I can't recommend it... The beeping that it makes is kind of ear splitting, and I can find no way to turn it off or to turn it down. I have another one of these by Klein Tools that doesn't have a digital readout, but the beeping on it is much more subdued. And so, as much as I wanted one of these with a digital readout, the beeping that this one makes is so bad that I won't even use it at all...

Seems like it works well. Its pretty sensitive, detects electricity from several inches away. Havent gotten shocked yet so it must be pretty accurate lol. Its kind of bulky compared to other voltage testers I've used, but I'm not exactly putting this in my pocket for EDC so not a big deal.

Great tool for seeking out hot wire to and flectric switch.

Great product. Reasonable price. Good Description.

Does what it should

I've only had this for a day and used it once. The product worked okay and as expected. The only issue I have is it arrived with a badly damaged AAA battery so I tossed both batteries and used my own. The box the device came in was not damaged so I can only assume the batteries came from the factory damaged.
