2 Pack Signal Blocking Bag

Wow, these Faraday cases fit our Samsung phones just perfectly, and work exactly as intended....when the phone is inside the silver-lined compartment, you can call the phone, but it won't ring. This is exactly what we need to be protected from either interruptions or surveillance. The case will fit nicely in a bag or a deep pocket. I don't quite see how I'll also get my key fob in there without scratching the phone, but I'll experiment. We may order some in the next larger size to have some more flexibility. Very happy with this purchase!

Works perfectly would definitely recommend this bag

I have to be honest, when I purchased a set of these I had the complete expectation that they will not function properly for the purpose of shielding my car's keyless entry fob from wireless range extender attacks, as a lot of products on Amazon only claims to be able to do so, while the only product that appeared to work costs $35 each. I skeptically placed my key into this $9 pouch and tried to unlock my car by standing next to my door, and was immediately disappointing by the fact that the car immediately recognized the key and allowed entry. Boy was I furious! Then I remembered reading something about a "silver" section of the pouch being the actual signal blocking section, and placed the key into that section instead. From that point forward the car didn't react AT ALL to my interactions, despite me jamming the pouch right next to the handle! I'd absolutely give this a 5 stars and recommend it to anyone who would like to protect their car from signal booster attacks. I only wish there's a smaller version that is purely designed for a keyfob, as I would happily purchase some for myself, friends and family.

Good price/ fast delivery A Faraday pouch can block pinging servers such as cell network / WiFi networks from reading personal info and IP address info stored on your smart phone, key fob, credit/debit cards, etc. as one wends one's way through one's day. Myriad electronic servers are reaching out to connect with small electronic devices / banking cards / key fobs which continually are also pinging back to cell network/ WiFi network servers. Main drawback I have found while carrying phone in a Faraday pouch like this one is that received calls go to voicemail, received texts get saved and phone does not ring nor announce arriving text messaging, emails also get saved to one's email account without notification. Personally, I'm OK with going through my day with a bit of peace and quiet. I'll call back from my voicemail and respond to text messengers / e mailers on my free time. If you must stay connected with your electronic devices and payment cards, this product is not for you. But if you choose to control your electronic devices instead of being controlled by your devices then this or another Faraday style protection container may work for you. Gdove52

My wife got these cause she was afraid of our cell phones, putting out some something at night. I don’t understand it, but anyway they must work because nothing works that you put in there. They can’t receive anything so I’m assuming nothing‘s going out either

I bought this awhile ago and initially did a few basic tests with it: - Paired a bluetooth gamepad with the phone, placed phone in back pouch and the gamepad lost its connection pretty much instantly even when being a few inches away. - Put the phone in the back pouch with service active, waited a few seconds, took it out and the notification light was blinking red and there were zero bars, pretty much indicating that they cell towers couldn't be reached at all. - Ran a wifi direct connection then used another phone to search for the signal and nothing could be found. I didn't call the phone while it was in the pouch, but as it couldn't even find a cell tower signal to read from I doubt that an incoming call would reach it. As an aside from those saying it doesn't block texts. Texts are automatically sent as soon as the phone receives a cell signal. You can't block them as far as I know; outside of changing your APN mms settings that is. I have noticed some strange indicators which lead me to believe that it may not be 100% effective at blocking wifi signals. I keep my phone locked down and in airplane mode when I'm not using it and when occasionally visiting local fastfood joints that offer free wifi (Which I never use) I often notice that my battery will take a 1% drop at or around the time I am there. All afternoon, night and morning it will be solid at whatever percentage its at, but around the time I enter the hotspot area, *BAM* 1% battery drop. Either someone's using hi-powered wifi which the anti-RFID material in this bag can't adequately absorb or the bag isn't blocking everything and it can read the wifi hotspot signals and is trying to examine the hotspot. Right now I'm assuming that it doesn't block everything and recommend doing as someone else suggested and purchasing a tablet-sized RFID bag and placing this inside it for %100 effectiveness. I haven't tested whether GPS signals are blocked, but it seems if bluetooth, cellular and mostly wifi are blocked then lesser powered GPS signals should be blocked as well, but I'm not certain. Size-wise, its big enough to hold even large phablet-sized phones though it would be nice if it were a bit bigger and able to hold multiple devices. It seems durable enough. I've opened it numerous times over the weeks I've had it and the velcro seems to be holding up. The stitching seems to be holding up. Overall, a nice enough RFID blocker. You should definitely retest it at regular periods to make sure the stitching and material is holding up and doing its job, especially if you have important stuff to protect. All this hacking going around is why having a device with a removable battery is important. Would love it if Samsung, Google, Qualcomm or whoever would put the wireless hardware on a chip that can be completely removed from the device to ensure 100% non-transmission since removable batteries are no longer the norm. Would totally obliviate the need for this as a less than 100%-reliable workaround for securing your phone/connected devices in certain situations.

This is fantastic. I bought it to protect my cell phone and find it easier in my tote bag. My phone is a Samsung Galaxy S25+ with a case. Both easily fit inside the Faraday bag . I do not put my credit cards in it since my wallet protects them. I put some currency in the front pocket. I do not go to concerts or demonstrations so it was not purchased for protection from tracking.

Does not work. Save your money. I had a Youtube video playing on my cell phone, put it in the "silver layer pocket" and it kept playing. This is the company's description and why I originally purchase the supposedly Faraday Bag... "Block Cell Phone Signal - If you don't want to answer the phone, you can put the phone in the silver layer pocket of the bag and close it, then the phone will be disconnected; this bag can also block Cell Phone GPS Signal to prevent tracking, protect your privacy." If there was a "no star" to award, I would have done that.

It was quite sizable and useful to contain both my big phone car keys and other essentials. It is good at the blocking off rfid signals and durable too.

Great product at an affordable price. The build quality and effectiveness of this product is just as described and what you would expect from something of this nature. It easily fits a smartphone or car keys / fobs inside it. When you put a smartphone inside, the signals drop and even becomes out of service. For smart keys, the car will not detect the key that is inside the faraday bag even if you are standing right next to the vehicle. All in all, this is an awesome product I would recommend to anyone looking for an extra layer of security and peace of mind. I personally had my vehicle stolen before and I had been recommended to buy something like this and I have been very happy since I bought this almost a year ago.

Ich bin sehr zufrieden mit dieser Abschirmtasche - sie tut was sie soll!!
