Great non-contact voltage tester with audio alert

 Would Recommend

I like that this tester has an audio alert. My previous one did not and it makes it difficult when testing outdoors or when testing at weird angles.

I needed to do some quick troubleshooting and didn't have my electrical tools with me. Getting quality tools at a great price, and i knew they would just work with no problems. And I wasn't disappointed.

Outstanding device

Amazing little gadget! Works exactly like it’s supposed to work. Keeping the kids away from it is the only issue I’ve got with it!

Anti-shocking

 Would Recommend

I’ve been using this daily since buying it. I’m installing my own ceiling fans so being able to have a little bit of extra comfort knowing I’m not gonna get shock.
