Electric and magnetic field tester ππ» Order arrived in 22 days at home. Tracked all the way. You can check the electrical and magnetic signals of various devices, like your refrigerator or phone. It works well. When I moved it against my phone the electric field sensor gave a very high value and it started beeping. When I moved it away and even removed the battery and put it back, it kept beeping. But maybe it's because my batteries where almost empty π€ I will try it again later with new batteries. I'm happy with the purchase!
Ok.

Ok.
The device does what it's supposed to do, but you can hardly see the display in daylight.
