Review on 📱 SYB Phone Pouch: Enhanced EMF Radiation Protection Sleeve for Regular Devices by Jose Schweigert

I don't have an RF meter but I was able to run a test that convinced me it blocks RF waves as advertised. Whenever my phone is on the table I get a lot of static electricity from my computer speakers coming from my phone (simple test, move phone closer, static increases; move away, static decreases). I even put radio chokes in the speaker wires to compensate, but to no avail. I've gotten to a point where I can tell when my phone is downloading something based on the noise in my speakers I hear before I get a notification from my phone. It dawned on me that this is a good test of the RFI protection in the case. As the speakers chatter, I place my bag on the side of the phone closest to the speakers and voila! No chatter. I removed it and the chatter continued. Put it back, it's stopped. I then repeated this with the phone in my pocket, the protective side (the side that's next to your body) closest to the speakers, and the chatter stopped. This convinced me that the defense claims were legitimate. I was going to give one star because I no longer have a choice of bag styles (I prefer a horizontal holster) but I thought the 5 stars were fair as it does exactly what it says on the tin.
