Review on 📻 LATNEX AF-3500 EMF Meter RF Detector and Reader with Calibration Certificate - Accurate Measurements of RF, Microwaves, 3-Axis Gauss Magnetic Fields, and Electrical Fields ELF by Larry Blanco

I was disappointed with the delivery!1. There was no indication that it was from Revain.2. It was open and still open when I opened the envelope.3. There was only one manual page (page 3). I found the first two online.4. It sends out many warning signals here and there in the apartment, around the house and also in the shopping center, the meaning of which is never explained.
