Blocks cell and bluetooth signals, great fro driving

For me, the items I tested did fit for my purpose which is I want a separate bag for each, backup hard drive in one, ham radio in another, etc

Would recommend the Mission Darkness Non-Window Faraday Bag for Phones, for anyone looking to protect not only their phone but other electronics devices like an external backup hard drive, memory sticks, cryptocurrency hardware wallets, and/or a handheld ham radio

The Mission Darkness Non-Window Faraday Bag for Phones is a nice size and I also tested it to see how additional devices might fit; like an external backup hard drive, memory sticks, cryptocurrency hardware wallets, and a handheld ham radio

BUT today I tested it 3 times in a heavy populated area while driving and it failed 3 times.

This would be good for removable hard drives, or larger phones.
