Отзыв о Electromagnetic radiation detector BENETECH GM3120 от Wiktor Wnkowicz ᠌

Different pros: Well, in general, the device is interesting. Maybe, of course, I bought it in vain, but I understood what places in the apartment are phony. In general, I took it to see if there was a background from jammers. But now I'm not sure that I'll find out, because the device does not show the background from the phone. Of the pluses, the battery is included, I thought it was not there and ordered it additionally. Some cons: When measuring the background of the TV, holding it in your hands and putting it on the table and moving away, the readings change as much as 3 times. Selfie stick also saves.
