Work as intended
Works as advertised after more than several projects. A no frills product from a trusted manufacturer that tells you if a circuit is live or not. Would buy again.

One of those good tools you wonder why you never had before
Saw a youtube video on how to determine what bulb is out on xmas lights and the guy recommended it. Works great.

Big improvement over my old one
Power switch on my old sensor from a different brand was the clip sliding back and forth. It never worked right, and you couldn’t tell if it was on or off. This one has a power button and lights up green when it’s on, and flashes red when it detects voltage. Audible alert is loud enough for my deaf ears to hear it. Glad I got this one. It fixes all of my complaints about my previous one.

New water heater and light fixtures DONE!
Been doing some electrical work aroubd house. I'm writing this review months later so it works swell! One thing I've noticed it will get off ghost beeps or w.e. false detection of power? Idk its probably my ignorance.

Must have
This is a must have for any jacks of all trades like I am. I already had one, but I couldn’t find it so I ordered this. This works perfectly and gives you a great layer of safety when doing electrical. It’s a bit pricey on Amazon, but I needed it quickly and it works as described. Klein tools are good quality.

soy ingeniero mecánico, actualmente laboro en la industria química en el área de mantenimiento, recomiendo totalmente este producto ya que es ideal para trabajos industriales a baja tensión (por debajo de los 1000 volts), salvaguarda el bienestar del usuario al brindarle la seguridad de trabajar en un entorno seguro y confiable sin riesgo de una descarga eléctrica

Qualidade superior aos similares
Já tive diversos testadores de energia, desde os clássicos ao digital em corpo de termômetro, aos novos testadores sonoros de marcas white label chinesas, este se destacou claramente. Ao ligar emite uma luz verde que indica seu funcionamento, sensibilidade grande sem precisar enfiar sua ponta chata (indicada para tomadas americanas) no orifício de plugs elétricos, ele detecta tensão apenas na superfície. Ele tem uma sensibilidade que varia entre 50 e 1000 Volts e funciona em alguns cabos de carregadores para celular com ainda menos voltagem. Essa sensibilidade é destacada por bips diferenciados como um detector de metal que bipa lentamente para mais distante (voltagens baixas) e mais instigantemente para voltagens mais altas como 220V da minha região. Sua estrutura é mais robusta e melhor construída que as concorrentes, na foto mostra uma das que mencionei. Para uma ferramenta de detecção de energia para se trabalhar em segurança eu dou nota 10. Se você precisa de algo mais especifico do que isso recomendo procurar outro tipo de ferramenta. Recomendo!
