Great tester for someone who is in the know

I received a similar voltage stick as this,CEF (UK)was the supplier, same circuitry etc, the unit is brilliant, with some knowledge, the unit shows on a bar or two ghost potential, mutual inductance etc, when on a live cable, like right next to the probe, it's red, for example on a three core flex, line, neutral and earth aka ground, the probe can be rotated around the circular flex and live can be located or neutral, even though it's very close to each other, used so many times it's simply practice to quickly test, so on a closely connected neutral and line it's child's play,The meter scale from yellow to red is really useful, as it's not a binary light up and sound OR not, relying very much on the tester to determine, but the accurate scale of (if memory serves) four yellow LEDs to two red leaves room for knowledge, intuition on experience, a quick rule of thumb, one or two yellow, ghost or residual or mutual/ inductance voltage, 3 or more yellow, neutral and finally one or two red, live, it varies one either way for type of circuit / equipment or situation, but the rule of thumb is like 95% spot on,I am a fluke,megger, metrowatt, kewtech, etc guy, but this voltage stick for a passive device is brilliant, the more you use it, then you just know how its nuances are,Invaluable and ability to create a higher resolution from the circuit dependent binary of live or not, sound and light up or not, just proves again, cost is no metric for quality or performance,Make sure if your meter is in reserve in a toolbox or in storage, REMOVE THE BATTERIES! batteries leak and knacker the meter, had a Klein pen voltage stick ruined by a leaking Duracell battery, fixed down to component level, but it's a non serviceable unit, so makes a mess getting into the gubbins,

Works perfectly.

Works perfectly. Always check a known live circuit first with this kind of tool.

Very sensitive and good value for money.

I have had it for a few weeks. The sensitivity seems good and the audible and visual alerts are clear if trouble is found. The build quality is OK for something that has a plastic shell. On the other hand, if it was made of metal I wonder if electric field detection would work as well. I am satisfied with this purchase.

Very sensitive!

This is very sensitive and using it in either mode will show presence of voltage in a wire. But at times it’s a little too sensitive. If I hold a usb c cable for my iPad in one hand and the wife tests me, I’m live lolBut as a secondary check after throwing the mcb on the board before getting jiggy with replacing a switch or socket for the price, it’s fine.

Non contact voltage tester

Discovered my old contact type tester (looks like screw driver with a red led indicating) was not working and never liked the fact I had to touch a live wire / terminal to get a reading. Found this "Neoteck" tester as a replacement. Can even tell which side the live wire is in a cable. Have had this only about a week and the novelty has not worn out. Have tested all cables that I happen to be using. No false reading yet. Therefore, think it is very reliable and above all safe and easy to use.
