Tuulin 2 Pack Faraday Bags for Phone and Car Keys, Signal Blocking Key Pouch, Anti Theft Car Protection, Cell Phone Keyless Entry Fob Signal Blocking Pouch

Works really well tested them out with a cell phone kept one for myself gave one to my wife

Initial quality (relative to price) is well made. Worth it. I tested iPhone 13 Pro Max using Wi-Fi, Hotspot, and Bluetooth and Apple's Find My devices and the same using a Pixel 9 Pro XL with Google equivalents. At point blank (making physical contact), some intermittent signals make it through. However, 2'-3' away, the signals stop completely and the connectivity drops. This makes it good enough for most use cases, but KEEP WAY FROM OTHER SMART DEVICES THAT PERFORM BLUETOOTH TRACKING! As for long term quality, as with all Faraday products, this cash degrade over time from wear and tear. DO NOT WASH, BEND, OR MODIFY THE OFF WHITE COLOR LAYER. That is the Faraday material. I expect a minimum of 2 years of useful life with moderate and careful use. If I can get 3-5 years of use, it exceeded expectations.

Arrived on time and as expected. Very slim design, almost flat with an iPhone 13 inside or key fob inside. Can accommodate both but will be bulgy. The velcro closure is sturdy, easy to align and close, the top flap folds down easily in the *one* position, I imagine you could force it to fold down more to make the pouch smaller, however *I* think it might compromise the effectiveness. I am not a tech person by any means, so maybe it would, but the velcro is only positioned for the original closing. No interior pockets, just the one. I tested both the phone and the key fob by having a friend call me while the phone was in the pouch, which she reported the phone did not go through on her end, nor on mine. I tested the key fob by placing it in the pouch and seeing if it could unlock the doors and start the car, it failed in both. So It also kept the key fob secure. I would recommend testing any RFID protective products to see if they can pass. I just purchased another product and it faile both tests miserably. Do your diligence. Bottom Line: I tested both my phone and key fob for security and both past the test, would recommend, with the caveat that *any* RFID blocking product be tested to your satisfaction before keeping.

It works with cell phones using 5G, also with wifi and bluetooth devices. But the bag is rather stiff, which is good in terms of protection, but it makes it more difficult to insert a bigger phone. But in any case it gets the job done. Any 2-way communication with the phone is cut off once it is inside the bag.

Priced very reasonably for the security that it gives. It works! Very satisfied.

This 2 pack was a perfect solution for our 2-car family. Each car has 2 radio-chipped keys. So that's 4 key fobs total. I tested both faraday bags with the keys right next to the cars. When I tried to open the cars by pushing the correct fob buttons thru the closed faraday bags, the cars would not open. For us, it's easier to store the 2 spare keys in one bag, and our everyday car keys (with our other house keys attached) in the other bag. But if you have 2 cars, it might make more sense to put both fobs for the same car together in 1 bag, and for the 2nd car in the 2nd bag. It's up to you. But the bags work great.

I've had the car key inside, and tried to open the door and my car alarm went off. Clearly my car didn't register that the key was nearby. Normally if I try to open the door with my car key in hand the alarm will not go off. Therefore, it does block the signal even when you are beside your car. That's a plus. However, the small size with the metal attachment is a very tight fit for my car key. Therefore, you may not be able to easily fit your key into the smaller bag with the metal attachment (for belt loop, purse loop).

A perfect size for placing my key fob to my car at night. Additional room if you want to place credit cards. Also, you get TWO bags, share with a friend! I keep one at home and one in my purse when out shopping so I know my cards and keys are safe from identity theft.

全く機能せず・・・。返品するにも手間がかかり大変。最近のアマゾン商品は酷い。

Want to disappear? Put your mobile phone inside the bag. Seal. Enjoy life! Any one including your boss calling will get the message “person you are calling is out of network coverage”. And that’s not your fault. Blame it on the network. Use responsibly. Can be used for preventing car with wireless keys from getting hacked and stolen as well.

Excellent for most phone sizes or wallets.
