"The media could not be loaded. I received the Kaiweets non-contact voltage tester yesterday. I inserted the batteries that came with it. The first thing I did was to test the tester. Using the 70 - 1K setting it could not detect any voltage at all when inserted into either the hot or neutral slots of a live 110V outlet, but it could detect it if set to 12V-1k V. What's worse, while in the 12V - 1K V setting it beeped strongly when touching a cable that was disconnected and completely dead except for being merely close to other live wires. I can't trust this at all. If you have one you should put it through some tests to make sure it works properly. I'm returning this product and looking for another."

So far, so good. As you can tell, I'm not dead from electrocution. We'll see if it holds up. Seems to be more sensitive than the big brands you get at HomeDepot but the price was good so I thought I'd give it a try.What Customers Talk About
