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.

Very handy for phone, key fob, credit cards. These are a fairly good size!

These bags work great for my cell phones and remotes for my vehicles !!!! They keep your phone blackout mode and your vehicle remotes from being cloned. Also I have put my credit cards in them!

I put my iPhone inside the case, then used my iPad to send a noise via find my iPhone. The sound was clearly heard and was almost immediate after the notification was sent out. Does not work at all.

My car door will not open when my keys are in the bag
