Timothy Paul: These Hot wire electrical testers are a must have when working on electrical wires. I use it all the time. From checking switches to fluorescent bulbs/ ballasts. These are just so handy. Doesn't replace a good Volt/Ohm meter. But handy in the top pocket while working on electrical.

Kevin: Does what it is supposed to do and warns of a live electrical circuit. Inexpensive.

The Yak: This wireless conductivity detector is a highly recommended to keep yourself safe while working on electrical. I just wish there was a way to shut it off and stop it from testing while packed into my toolbag.

THE REJ: Very handy device. Gave it 5 stars even if it got limitations due to design. It likely works by detecting any form of induction in the tested wire..... So, wire coming from a loaded/crowded junction box can carry inductive charge with very low voltage that would be detected making you thinking there is line voltage on it..... No big deal as the reverse would be much more dangerous.... So, in these odd case I just confirm with a regular contact based meter.... Love it anyway!

NOE ROBLES AMADOR: A veces me ha tocado que sé que el cable no tiene corriente y cuando acerco el probador se le dispara la alarma...

Joaquín: Un buen tester para corriente alterna, aunque podría ser un poco mas barato, pues hay otras marcas que hacen lo mismo, pero cuestan menos.

Eric Vey: I bought one of these about 10 years ago and it worked fine until it was washed in a shirt pocket. When I replaced it, I almost sent it back because it was a lot less sensitive, but I decided to try it out since I had 30 days. When I had the old one, first one I ever had, it was useless as a diagnostic tool, but great as a safety tool because it would go off 6-8 inches away from a hot wire. I thought that was the way they were supposed to work until I got this one. Now, I can pick out a dead wire in a panel of hot ones, but I have to touch the wires to the nose to find out what is what. It may go off an inch away, but until the wire is touched, one can't be sure. Forget about detecting voltage in a wall switch unless the switch is pulled out. Reading over the reviews here, I suspect that others have had similar results. Some complain it is too sensitive and others not sensitive enough. I'm going to keep this one because I can pick out the hot from the neutral in a recepticle, but knowing it's limitations.
