4 Pack Faraday Bags, Large Faraday Cage for Laptops & Tablets & Phones & Car Keys, RFID Signal Blocker EMP Bag, Go Dark Bag for Cell Phone Block Signal and Anti-Tracking

These bags are great and I love the quality! I was putting my phone in one at work while not in use. It did so good it took my phone some minutes to get back to normal with service. Would for sure purchase this again!!

I work for the prison system and this is used to protect electronic devices. It really works and it is good for when going on vacation. It keeps pirates from electronically tapping into your phone, laptop or iPad. I use the smaller one for my keys to keep thieves from using smart devices to steal my car. No signal is transmitted.

I did the cell phone test and it worked!The sizes seem to be well thought out for my purposes. I tried the cell phone test in the big one and it worked perfectly. I’m very happy with this purchase and have filled all of them completely as they sit and wait for a catastrophe that I hope never comes.

My only problem was that they looked leatherette in the pictures but are, in reality, a weird tacky texture.However, they do exactly what they promised to do, so I don't mind. They keep things from connecting to my device and prevent things that want to wirelessly charge from giving me a burning sensation on my leg when they're in my pocket.

The daughter was shocked when I showed her my faraday bags she doubted they worked until she tried mine. Ended up requesting a set for her birthday. We both love them and the price was lot cheaper than others I researched and work Ike the expensive ones or better!

Perfect is all I can sayWorth every penny

Good Product

Great to have, works well! Like having the variable sizes for different products.
