## Description

TES-111 80-250 VAC Twin Probe Voltage Tester.

Review: Tiny Tool, Big Peace of Mind (and Zero Electrocutions!) - 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.
Review: essential tool - Does the job!!! We lost ours and didnt have one when we needed to check some circuitsso we ordered this.

### ⭐⭐⭐⭐⭐ Quick and easy
*by D***T on November 17, 2025*

Is it hot or not? I have more sophisticated electrical testing equipment, but it requires batteries, turning it on, and setting the dials. With this dandy little device, just touch with the probes and see instantly if an outlet or circuit has juice. Doesn't tell you how much juice but let's you know at a glance that the device is powered. Time-and-hassle-saver.
