Large Faraday Bags - 5 Pack Faraday Cages for Laptops & Tablets & Phones & Car Keys, Faraday Key Fob Protector, Fireproof & Waterproof Anti-theft Signal Blocking Pouch

Love it . Love all the sizes. Works great. So far I’ve ordered this faraday bag variety 3 times. When I show mine off, my family and friends want it too.

I am so happy with this faraday bag, every time i've put my phone in it and then remove it im shown the emergency calls only ,meaning that it completely blocks signal.. i purchased the larger one as well for my router..

These Faraday Bags are great! The first time I used one of these, was in 2023, when I went to a comedy show in NYC. Everyone at the show got one, and the staff locked these bags shut, so nobody could use their phones, during the show. So, I made a mental note to get at least one for my cell phone, but ended up getting this 4-pack. I'm glad I did! Now, I can have my cell phone and my PC/Surface Pro, completely blocking all signals. *** NOTE *** 1) I tested my phone and my friend's phone, to show him. a) no text messages, phone calls went through on either phone, while inside the bag. b) Blue immediately disconnected from my GPS watch and my earbuds and my car as well. c) I tested my laptop/tablet as well, and no signal in or out as well. 2) the 4 sizes are essentially like this... a) fits key FOBs, GPS watches, and maybe a very small cell phone b) fits most cell phones c) fits tablets and very small laptops d) fits most laptops (fits my Surf Pro 8 fine, even with a protective hard-shell cover for it) 3) the inside of these bags, have a smooth, metallic "looking" lining to them as well. I highly recommend these Faraday Bags, because they work fantastic! These might be a bit more expensive than some of the other bags listed on Amazon, but sometimes... it's better to spends a bit more on something that works quite well.

Tested these with my iPhone and MacBook. No texts came through to either device while in the bags. In fact, it took around 2 minutes for the texts to come through after the devices had been removed from the bags. I also called from my home phone and Facetimed both devices from only a couple feet away and not only did no calls go through, but the iPhone said "No Service" when I removed it from the bag, for approximately 30 seconds. Wow. I did set a timer and an alarm on the iPhone to see if that would still work from within the bag, which they both did, and could easily be heard. (In case you had one next to your bed and/or need an alarm. Although I've heard it drains the battery when left on inside the bag; I haven't tested that yet.) I'm not sure if they also block EMF signals emitting from the devices, but it does give me peace of mind that no one can hack my devices or steal data when inside the bags, including my car key fobs. These were a great deal for the price compared to other brands, and the only downside I can see is that the silicone outer coating on the bags is extremely sticky and tacky, picking up any and all lint, dog hair, etc. from surfaces that they get placed on or in (like the abyss of a woman's purse), or that you wipe them down with. The large one actually had boot footprints on it, fresh out of the bag. Either way--they work!

Admittedly, I was half expecting these not to work, considering the price, but the first thing I did was put my cellphone in one of the bags, closed it up, and called it from my wife's cellphone - silence was all I got. Most importantly though, and the reason I got these bags, was to test the key fob for my car - I put the key fob in one bag, stood about 15 feet from my car, clicked the lock button about 25 times, absolutely nothing happened. Took it out to test the same distance, my car honked every time I pressed the button. Quality seems solid, velcro holds well, I'm loading mine up with various electronics I have stored away....just in case. I will likely be buying more. Update: Did a third test, took a tablet, did a continuous ping to my router to see if I would get any dropped packets, worked fine and there was zero connection AS LONG AS the bag/tablet were in another room, however, when I did the same test with the bag/tablet right next to the router, it never lost a signal, didn't drop any packets - I did both of these tests about 5 separate times with the same results. Will be looking for something a little more heavy duty for some of my equipment, but for the key fob, it does the job.

These are exactly what I needed to protect my devices from trackers! They're durable, they come in different sizes from holding earbuds or a whole laptop, and I can just leave then in my car or take them wherever. Great purchase

Seems to do the job very well, a little snug on my phone, but I can carry in my pocket, so I'm satisfied.

These anti-theft, signal-blocking bags are effective in shielding sensitive electronic devices, such as fob keys and credit cards, from information theft. I use one of them for putting away and securing my portable toll transponder, when not in use.

Works well. My phone lost its coverage completely inside it.

Buena calidad , de buen tamaño, pesan un poco

Really works. Put a cell phone in one and tried to call it...nothing! No ring, nothing. I am so pleased!

Produkt funktioniert wie gewünscht: wenn man sein Smartphone hineintut und nur oben die lasche leicht zudrückt ohne die Tasche richtig zu verschließen, dann befindet sich das Smartphone bereits im Funkloch.

Funcionan tal como lo dice la descripción
