Lack of instructions but there is a bar code you can scan to supposedly get instructions but doesn't work & no help from seller!

It's great. In places where I know there are wires, it found them right away. There is just a chance that the neutral might be facing outward and make a slower sound. Either way, it works perfectly for me, so I tried it.

It detects alternating current (AC) voltage. It is suitable for professional and home use, especially when there is a need to locate the presence of voltage in wires, sockets, or electrical devices. It covers a range from 100V to 1000V AC. It detects voltage without needing to touch the wire. It is small and lightweight, easy to carry and store. It saves battery by automatically shutting off after a period of inactivity. It is easy to use, even for beginners. Overall, it is useful for everyday maintenance tasks. An essential tool for electrical work.

I bought it because in daylight with the test screwdriver you can't see if the bulb lights up.
It is very good in terms of functionality and with excellent quality materials. It adjusts its sensitivity, so it helps both for walls and for cables that are stuck together and you need to find out which one has the voltage.

I am an electrician and the fact that it has saved my life is an understatement. What can I say when you are asked to strip cables on live currents? It is flawless and I haven't even had to change the batteries yet. The flashlight is very helpful

Having previously purchased a cheaper model (YATO) completely by chance and seeing the many advantages of the induction screwdriver, I decided to get something newer and more economical. FLAWLESS. Nice size with its screen and lens, and of course the automatic shutdown so it doesn't drain your battery. It also has a sensitive button that increases its sensitivity to find an active conductor over thicker insulation.
