Review on 🔒 Red X-Small Silent Pocket Signal Blocking Faraday Key Fob Case - Advanced Car Anti-Theft Shielding Technology Blocks All Signal Types, Including RFID Blocking - Durable Faraday Bag, Fits Most Car Keyfobs by David Tadder

Pros: Looks good, fits iPhone 11 and SE. Seems to block cell signaling most of the time, snaps are much more convenient than velcro. Cons: Bluetooth and a strong WiFi signal knock this out, especially when broadcasting nearby. For example, when I'm listening to a podcast through wireless headphones and plugging in my phone, the audio immediately starts to stutter and cuts out. If I take an already closed device and hold it within 3ft of the headphones, the signal is loud and clear. Repeated the test with two iPhones, different headphones and they do the same thing. Wi-Fi does something similar. If I'm streaming something locally (no buffer), I can still hear the audio stream even with the case closed. The stream is stable when I'm within 20 feet of the access point. May I recommend? No, not this one. If you're just looking for cell blocking, this might work well.
