Great tool when working with live wires

Not functioning after 3 months. Not recommended.
Would Not RecommendI bought it and used only for a couple of times. Just around 3 months after I bought it, it was not functioning. I changed the battery and it worked only for one more time. And it was broken again after one or two weeks. Looks like it was draining battery or some electrical issue occurs.

Be safe. GET ONE!
Would RecommendObviously easy to assemble and turn on. I've owned one before that crapped out after I left the batteries in for a couple years. That was on me. This one worked fine and is a very inexpensive way to be safe.

works great on exposed wires. sometime false positives in close spaces like a junction box.
Verified Purchaser
It works sometimes but it showed false negative on power feeding to water heater and that could have been very bad. Better to go with a better brand

excellent gadget that INCLUDED the batteries! I was able to hard wire install my smoke detector without worries of electrocution.

Works as intended
Would RecommendNeeded this because I’m discovering my new house can’t be trusted and I don’t want to get electrocuted while attempting to install my new vanity lights. I can attest that I am still alive.
