Review on 📡 GQ EMF-390 EMF Meter & Detector: Tri-Field Electromagnetic Radiation Detector for 5G Cell Tower, Wifi, Data Logging, Spectrum Analysis, Radio Frequency Detection - Ideal for Ghost Hunting & Beyond by David Grajales

According to the manufacturer's description, the device works with a frequency of up to 10.0 GHz, which is not the case. It only works in any mode up to 2.5GHz. I read many customer reviews when making my purchase but only one customer said 5Ghz doesn't work; Now after only 3 days I see a lot of customer feedback that 5GHz is not working? In any case, the meter is good for checking Bluetooth, old WiFi and microwave ovens. I would give it five stars if it ran up to 10GHz as advertised. As its performance works well (I haven't tried any PC software) I think I'll leave it, but if I'm new it doesn't really read 5.0GHz then I definitely wouldn't buy it. This (GQ EMF-390) showed me that my "TechBoss" Bluetooth audio transmitter, which is 4 feet from my head where my chair is, emits the same amount of radiation to the right side of my head 24 hours a day , 7 days a week frequency of 2.4GHz how much comes out of my microwave. Ovens for cooking at a distance of 3 feet. Also, my old RocketFish Bluetooth audio transmitter was there, and this meter showed me that it was also radiating out of my head like a microwave, even with the Rocketfish Bluetooth transmitter turned off. Of course, I always leave NOW TechBoss off and RocketFish unplugged, except when I'm upstairs but still want to hear audio from my home theater downstairs.
