NSi Industries TES-111 Twin Probe Voltage Tester, 80-250 VAC,Neon

Works as listed. It works by direct contact (Open wire, outlet slots and light bulb socket). Pros: It does the job intended and is reasonably priced. Cons: Cables are on the short side and light indicator is hard to see outdoors during the daytime. Either cable (Red or black) can be used on hot or neutral wire. It has a built-in clip attachment to carry, if you prefer. It does not require a battery, which is a plus, but could be a minus if the small light indicator dies (?). Overall, it is a good product that serves its function. Recommend and would buy again. Thank you.

This little neon wonder is the unsung hero of my toolbox. I bought it to check if an outlet was still trying to zap me from beyond the grave before I swapped it out. Spoiler alert: it wasn’t—thanks to this handy tester and not, say, trial-and-error with a butter knife. It’s super compact — roughly the size of a suspiciously long stick of gum — so it won’t hog space or make your toolbox feel bloated. The twin probes are easy to use, even for someone like me who approaches electrical work with the grace and confidence of a nervous raccoon. It lights up if voltage is present, doesn’t if it’s not — no app, no charging, no existential questions. Just pure, neon-lit honesty. For the price, it’s a no-brainer. Unless you want to find out the hard way whether something is live. In which case, good luck and wear rubber shoes.

It's small and very convenient. Doesn't take up much pocket space. It works great it's a useful item.

Part of my line of work. It's nice to have something very quick that can test exposed wires before I have to cross them. This works fairly quickly. Very cheap though. You can actually easily make one yourself. It's just nice

Great value with fast shipping.

Didn't get electrocuted while switching out my room outlets. I count that as a win.

Simple way to check outlets.

Got this cause I needed to check some plug-ins to see if they were getting power to them. It works really good and it’s a very good price.

Tel que décrit.

the cable is too short

Très bien
