Easy to use and works really well
This device is GREAT. Put the two AAA batteries in (came with it). I also watched the video. Used it today as I needed to replace a basic light switch. Came in VERY handy. I also have been watching my dad use his old two-wand test meter from the 1970s. This is SO MUCH EASIER and it works!!!!!! When the line is hot, the red light goes on and you get a warning noise. If the line is cold the device light remains green. Just told my daughter to buy this for my dad for Christmas.

Electrical test
Excellent for detecting active current. I can work safely. When it detects the current, it emits quality sound and red light. It gives me precision to identify wires. Very easy to use Also to know the errors in the outlets.

Trusted Brand, High Quality
Trusted brand, durable casing, battery life is dependent on usage, LED notification is simplistic; accuracy is perfect. Product is higher cost than other brands however, this is due to performance and product reputation

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.

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!
