Large Faraday Bags - 4 Pack Faraday Bag for Phone & Laptop & Tablet & Key Fob, Faraday Cage RFID Signal Blocker, Faraday Pouch with Lanyard, Key Fob Protector Anti-Hacking Faraday Sleeve

They work, nice sizes

Exactly what you see. The largest bag can accommodate a laptop. The second size a tablet. The third size a normal sized cell phone. The smallest is specific to a key fob. Sturdy and well made.

I purchased a Mazda CX5 a year ago and I was going back to the dealership every two or three months over the key fob. It would go through the battery that fast. The dealership would just change the battery and say it's fixed. They also advised me to keep bringing it back and they would take care of it. I don't want to spend that much time at the dealership. This signal blocking bag seems to be blocking the signal throughout the day and night. I'm pretty sure it will block the hackers from steeling your credit card info.

Seem to work great for my needs.

The images and video suggest that the bags are seethrough (block shown in images, grew shown in video, both show it see though). That can be useful when you have an auth app on the device so need to see the code but don't want it EM accessible, which is why I bought this brandHowever, the product as shipped is not see through.

The smallest pouch blocks my Ford Explorer key FOB signal. The FOB fits inside with room to spare. Other Ford Explorer owners know how important it is that the FOB fits because the device is so large. The next larger size pouch will fit the FOB, a mobile phone, and a wallet for going to the beach. I like that all the different-size pouches are included for one low price. All the pouches are made durable enough to last a long time under heavy use.

Very nice bags. Works for every item I wanted to protect. The different sizes and price were what sold me .

I ordered the silver and love them. I would have liked a second hook on the larger bag to carry off the shoulder, but I am so satisfied one hook is not a deal breaker. No complaints on the pricing because they were above my expectations for that cost.
