Review on 📵 EMF Radiation Blocking Cell Phone Sleeve for iPhone 12 Pro Max | Signal Shielding Faraday Bag Case Pouch | Security Wallet for Car Fobs | Anti-Tracking, GPS, RFID | 6.5inch Case Cover by Lance Jenkins

Works as intended/described:1. When the phone is in the pocket and the pocket is closed, the phone does not receive a wireless signal (calls do not go through) and you are protected from EMI.2. When the phone is in the pocket and the pocket is open, you can still receive calls. Electromagnetic fields are shielded but not suppressed. Lightweight, metallic silver and gold are reminiscent of ripstop windbreaker fabric. I lost the one I had (from another company) and actually preferred this one. Perfect fit for Samsung Galaxy A75G. The price is very very good. My grade is A++.
