Review on 📡 GQ EMF-390 EMF ELF RF Meter: Advanced Multi-Field Electromagnetic Radiation Detector with Data Logger and Spectrum Analyzer – Detects 5G, Smart Meters, WiFi Signals up to 10GHz by Ricky Lahoti

First of all, five stars for customer service! This is the best purchase I've made from Revain recently. I have a number of health issues related to dirty electricity and EMF. This measuring device helps me a lot to assess these risks. There is a learning curve to understanding the different types of EMF and their units. I was surprised to learn that some of the strongest sources of EMI/EF around me are my car, induction cooktop, and office wiring. However, this mobile counter is somewhat filigree. I dropped it and must have lost the connection because I could only see information on half the screen. GQ immediately sent a replacement. I highly recommend this company. I only wish they sold a protective case for this meter because sometimes you have to carry it with you.
