Doesn't Beep

Would Not Recommend

This unit has never beeped. Can't find anything in the sparse paperwork.

Everything metallic was shown as having current

Would Not Recommend

Everything metallic was shown as having current. Not telling me whether the line has current flowing through it just that it is metallic.

Absolute trash

Would Not Recommend

I’ve had other sensors before that could actually trace a wall. This one didn’t even work on a live outlet! See video

Most durable

Would Recommend

I have tried many of these by Commercial, Ideal, Klein and Fluke. This is the most durable. I bought this as backup for when I lose mine. Mine I've had for over two years, in my pocket every day, and it works well. It has survived 6' drops too.

Love this Voltage Tester

Would Recommend

My last tester stopped working after 12 or 13 years, so I picked up 1 of these for me, and 1 for a neighbor. It is a great way to troubleshoot and tell if voltage is present, without touching anything. Every handyman should have 1 of these, every electrician does.

Well made tester.

Would Recommend

Although not an electrician, I replaced a binary light switch with a dimmer switch. So I wanted a "hot wire" tester to ensure I didn't miswire the new switch. Although more than I wanted to pay and probably overkill for my needs, the tester is well made and did the job I needed done.
