Magnet detector not voltage detector
Excellent magnet detector it helps me to trouble shoot solenoids, for people who doesn’t know this is not a voltage detector.

Don't waste your money
Poor quality all around. Package a pain to open, battery compartment opening very difficult to figure out and, oh yeah, it does NOT detect any magnetic fields. Poor value, does not function, difficult to use. Flashlight works ok, but doesn't stay on unless you keep your finger on the button.

Handy tool.
Very neat tool to have in your tool box. I recently just used it to see if my ignition coil was working. It was I had a bad spark plug. Awesome for diagnosis.

Magnet detector, not voltage!
When you but magnet detector, why you try to detect voltage with it?

The flashlight light works.
Piece of dodo. I wrote you the day I received my not working no contact electrical detector. I was interested as it did DC. Mine NEVER worked!!! I tried 3 sets of batteries, Flashlight worked that's it! I reached out but you never responded. I hope other people have better luck. Not worth it.

Tool fails to test at times when testing and is dangerous when working with AC Power.
This so clled AC/DC tester is pure junk and unreliable. Sometimes works and most times does not work. Get made in USA . This tester made in China and just a dangerous piece of junk . You want a solid good test when working Power, not a sometimes working tool. Save your life and BUY MADE IN USA. Amazon should stop carrying this junk type tool.

Better than expected
Works better than I expected it to for checking DC hydraulic solenoid valves. It is a little tight getting the cap off to swap batteries, but nothing you can't handle with a little flathead screwdriver. The light on this is useless though, but that's not what you're buying this for.
