Keyohome EMF Meter High Accuracy Electromagnetic Field Radiation Detector Battery Powered Electric EMF Detector Ghost Hunting Paranormal Equipment Tester for Industrial Construction NO BATTERY (Black)

My son wanted it, don't know why

5*

Tested this on my router, put it against it, and it went to red, backed off about 15 inches and it went to green. So happy with my working distance at my computer. Also tested on the microwave, Held aginst it while working, and was reading red. I backed away a couple of feet and back to green. Lesson, do not stand in front of the microwave oven while it`s working.

It looks like a cheap plastic toy. I wouldn’t trust this to give me an accurate reading of a genuine concern of mine of EMF …and it didn’t even come with a battery .. if that wasn’t bad enough it uses one of those square batteries ….who has them in their house? This will be going back

Good for Paranormal investigating, had seen them on a Paranormal equipment sellers page, and then looked for them on Amazon glad i did they were half the price of the other seller

Went to go out on my 1st investigation so tested all my gear Nd my EMF did not work so im rather not ppp off about it so now gonna have to find someone else who can send me anotherone what works

It works

Battery contacts needed adjustment to keep battery connected. It's cheap so it's cheap build quality. Saying that, once connection issues were addressed it did work .
