Voltage Tester, Non-Contact Low Voltage

Nice tool, good quality. Seems that I need to get into an electrical box every other year or so. I fav a forty plus year old contact tester. But I learned about these non contact testers and had a good experience with Klein. This tool is really good. It has a green led to make it clear that the unit is functioning and the batteries are still good. That’s important to keep you safe. It makes it very clear when there is a hot wire. It made my swap out of old smoke detectors safe. While I first isolated and cut the breaker, this tool made it sure there were no hot wires in the box. Nice and safe. Highly recommend this tool. And Klein seems like solid quality.

Works perfectly as expected and cheaper than I could find locally. Notably, the tone and sensitivity is low enough that I can identify wires that are hot/off within the same box just an inch or two apart. I always keep this in my back pocket working remodeling just to check and double check during work.

Good voltage sensor, easy to operate

Works great! I've already done 2 home projects since receiving it. It's very easy to use.

I trust the Klein brand electrical tools and would not trust a Chinese knock-off brand on a tool like this. Mine will see sporadic use - I'm not an electrician - and I plan to remove the batteries when I'm not expecting to need it for a while (corroding batteries have ruined my clocks, flashlights, ...). The release to get the battery compartment open is really stiff and I have to press it so hard I'm worried about breaking it.

Works as advertised after more than several projects. A no frills product from a trusted manufacturer that tells you if a circuit is live or not. Would buy again.

This Klein voltage tester is now my emotional support tool. I walk around the house tapping outlets like a low‑budget electrician, and it beeps with the confidence of a smoke alarm. The green light says “you’re fine,” the red light says “don’t touch that unless you want a new hairstyle.” Small, loud, accurate — and it makes me feel way more qualified than I am.

Excelente producto a buen precio, excelente herramienta para detectar voltaje

Exelent price, good quality, it works great

Ferramenta eficiente!

Muy practico

C'était parfait pour tester le courant avec une seule main (sans danger de s'électrocuter) et très simple d'utilisation. J'avais déjà divers testeurs, mais ils étaient plus gros et exigeaient les deux mains, ce qui n'est guère pratique lorsqu'on a à tester des fils au plafond, les bras en l'air, par exemple avec des fluorescents et des ballasts qui ont parfois de nombreux fils.
