Works as described. Worth every penny.
It works flawlessly. I placed a transmitter with an output amplitude of -25 dB inside, and its signal was completely suppressed—reduced to zero. Literally no signal escaped to the outside. It blocks virtually all radio frequencies. A phone placed inside instantly loses its connection and becomes unreachable. It isn't cheap, but it is well worth the money. It is made from high-quality materials.

It works!
It works! Put my fob near the car door and tried to unlock it and nothing. The bag flap needs to be tucked into strap and mine doesn't quite get put in smoothly but I do have a fat key fob for my car. Otherwise, works great, highly recommended.

Good protection for your fob
Decent RF key fob holder. It's sturdy, looks good, and is large enough for the fob and a few keys. It would have gotten five stars from me if they had only included a strip of Velcro for the flap, because it really doesn't tuck into the overlay band very well. Fortunately, I had some extra Velcro on hand.

It definitely works!
The Faraday Bag for Keyfobs is not what I expected at all. I was just looking for a shielding bag, but what I got was much more than that! At first, I felt that the Faraday bag was going to be of poor quality due to the way it was packaged. However, after feeling the texture of the bag and putting it to the test, I was very pleased to see that I got a good quality item for the price I paid. When I put my keyfob in the bag and pressed the button to open my car, it would not. It simply lost all connectivity to the car as if the keyfob stopped working. When I took it out of the bag, the keyfob was working just fine. This is an amazing product because it does exactly what it tells you it's going to do. The material is also fantastic because when I poured water on the bag, the items inside were dry and protected. It may look like a simple bag, but it is definitely much more than just simple. It is well worth the price paid for and have already recommended the product to a few friends in need of the shielding bag.

Love it!
Great purchase. Fast shipping, fits my key fob with no issue. Sturdy material, look great and most of all it works. I’ve tried others that did nothing. I am very happy with this product line and will be buying more.

Buyer Beware! This product stopped working after only 2 months, 19 days of very careful use.
Buyer Beware I bought a Mission Darkness cloth signal blocking Faraday Bag for my keyfob from Amazon, along with other products from their company & received this product on 10/31/25. The cloth signal blocking envelope only worked for 2 months, 19 days & now it won't block the signal, no matter how exactly I close it. I even put my keyfob in a plastic bag each time, before I put it in the Mission Darkness envelope to avoid any wear on the fabric. I was very careful to take care of the envelope. I am very disappointed in the quality of this product and how it stopped working after only 2 months, 19 days, which is unacceptable. I sent feedback to the Mission Darkness people and I hope they respond. I think they should replace the product as it did not last. This product doesn't appear to block the signal for very long or hold up to even the most careful use of it. If they correct this issue and the new product works for longer, I will update my review. Update: The vendor never got back to me or replaced the product despite me contacting them.

Great value, reliable protection!
These work so well. I use one for my car key and use the other for credit cards when I travel. I have tested the signal blocking by attempting to unlock my car while my fob is in the bag, and it is a no-go. Even when I am next to the car, my car is unable to sense the presence of the key, which is exactly what I am looking for. These are small enough to easily fit in my handbook, but large enough to hold all of my cards and keys. I highly recommend - especially for travel, visiting theme parks, fairs, or any other place where your information might get scanned!

Works for my car fob
It works. I used it for my car fob and when it's in the pouch and the cover to the punch folded over and tucked into place as the instructions say, I cannot open the car door. So far so good after using it for a few days.

Quel prix vaut vôtre sécurité ?
Excellent pour les clés de voiture modernes et pour les cartes de crédit. Une fois à l'intérieur rien ne fonctionne et tout est protégé.

It works!
I did my search and decided to give it a shot. It block the signal of an m3 2024 gt turbo fob even if the case is not fully closed. I think they enhanced the inner layers somehow. Nevertheless, I have read that eventually over time, the faraday cage tends to lose its strength, so you better close it properly. It is kinda bulky, but the fabric material is comfortable in the pocket. For newbies: for opening the door, the key needs to be taken out of the case, then turn on the engine, and once it’s started, you can store your key again inside the cage, the engine will work with no issues. But when you park your car, and turn off the engine, if the key is still inside the case, it won’t lock up automatically your car, you need to take it out nearby for taking advantage of the auto-lock feature, then you can store it again. At the beginning is kinda annoying, but you get use to it. I would definitely use it almost on a daily basis, safety first :)
