I'm quite impressed with this bag. I put my new car key fob attached to a keyring with keys inside the bag, secured the velcro well, and rolled the top down to fit in my purse. Once inside my purse, the key fob DID NOT recognize the car and did not unlock the doors. Perfect! Great product! My only ask is for more colors.😁I usually don't take time to write reviews here, but this product deserves a 5-star review.

I haven’t tested this yet with emf meter but I put my cell phones in it nightly and even daily when not in use. It fits one perfectly but two I can’t close the flap.

With my car, if the fob is too close (even on the kitchen counter which is next to the driveway), anyone can get in even if the car is locked. Of course, they can't start it. I also use the remote start in the winter so this pouch makes me feel double secure that no one can steal my car. Thank you for a VERY useful item!

As tested on Android phone (using MD Faraday Bag Tester like another reviewer), this pouch generally works, but most successful only when closed well (see below). Blocks Bluetooth and Cellular indoors, although I did have my BT earpiece come on. Also Blocks most wifi signal, up to ~60db, I've only had it fail at direct proximity with signal source, likely because the bag wasn't sealed all the way. Average shielding overall is around 40 db, depending on signal strength from various sources. So I am getting somewhat better results than some of the more negative reviews. Also, disclaimer, I only get average cellular signal in my area.Tested and works with several car FOB, both old-school (with button) and keyless entry (model years 2011-2018). Also works with home security FOB. Did not try with RFID key card or credit card.In terms of design: Magnet and roll up velcro to close works relatively well. Fits Pixel 4 and Samsung Galaxy 21S - you can squeeze in both together, but it's a tight fit. Would fit a phone with a thicker case. The reason that I mention that most likely the differences are due to the seal is because when I close the velcro AND do another roll (possible with Pixel 4 in a case, which is just under 6" height and 1/2" depth), I have 100% success rate, even line-of-sight sweet spot of a modern, dual-band wifi router - but you would have to use tape or some kind of clip to keep it that way.For the price, this definitely beats a cardboard-lined tin can, and works better than I expected. However, if you have high-value assets, you may consider a step up to something with a more sure-fire latching.Screenshots:1 - inside, away from wifi behind multiple walls;2 - line of sight from wifi (note in the graph, BT briefly came back on in this one);3/4 - outside deck, behind one wall of wifi (attempt #4 had better velcro seal);5 - Inside line of sight;6 - Inside around the corner from wifi;7 - Line of sight of wifi, with double roll (see above).

I wanted a product I could put my cell phone in while carrying it in my purse. I chose this to protect me from EMF but also to protect my phone. I highly recommend this! It’s well made and brings me the comfort of knowing I am indeed protected.

Did not work. Didn't block calls or signals

My phone is in there all the time. Hoping this cover does work! Made well,

The product is a very high-quality product. It perfectly fits a Galaxy S7 Android Phone with an Otterbox protective cover, leaving room for nothing else. High-quality stitching, seams, magnets, and it looks good too. It appears to be durable, but I just received it, so I cannot defend durability objectively.I ran several tests.With the phone in Armadillo Pro-Tec Faraday Bag, I called my phone and the cell provided could not resolve to my phone...which means it could not find it...so the call went to my recorded away message. No record of that called was found on my phone.With the phone in Armadillo Pro-Tec Faraday Bag, I SMTP texted my phone from another phone. The phone in the Armadillo Pro-Tec Faraday Bag did not receive the text message UNTIL I pulled the phone out of the Armadillo Pro-Tec Faraday Bag.Here is the SNAFU...I used my Galaxy S7 to generate a hotspot that I normally use during app development. I inserted my Galaxy S7 into the Armadillo Pro-Tec Faraday Bag with the hotspot active. I used my development laptop to sniff for the hotspot generated by my Galaxy S7...and...there it was...persistent...and I connected to the hotspot...now I give Armadillo credit for blocking the WiFi signal to the phone, because I was not able to resolve to the interwebs from my laptop through the Galaxy S7 phone hotspot...until...I pulled the Galaxy S7 out of the Armadillo Pro-Tec Faraday Bag...then...there was the interwebs. During this test, I acquired the SSID and MAC address, as well as other information, from the phone.Summary Critique:1) High-quality product.2) Well constructed.3) Blocks WiFi signals to the phone.4) Disrupts and/or disconnects from the cell provider.4) Does not block a hotspot (MAC address, etc) broadcast by the phone.What does this mean?1) If you expect the Armadillo Pro-Tec Faraday Bag to disconnect you from the cell provider network, it will. This means that the cell provider network will not know where the phone is in its network.2) SMTP texts sent from someone else (by the way email too) will be queued by the respective servers and eventually sent for you viewing when your phone is pulled out of the Armadillo Pro-Tec Faraday Bag.3) Although I did not perform this particular test, intuitively from developing similar IoT boxes, I am confident that because of #1 above, the Armadillo Pro-Tec Faraday Bag also will block the GPS receiver chip in your phone from receiving GPS satellite location messages. Note that cell triangulation and GPS location are totally different. I am stating that from experience, if the cell signal is blocked, so is the the signal FROM the GPS satellite network. Apps on the phone will not even be able to buffer, queue, or save your location information for later transmission when the phone resolves to the interwebs over a WiFi network.4) DO NOT EXPECT THIS PRODUCT TO MASK THE IDENTITY OF YOUR PHONE. Say for example you are sitting in an airport. You put your phone in the Armadillo Pro-Tec Faraday Bag because you are depending on it protecting you. Hypothetically, I am sitting behind you with a laptop. I will be able to see your MAC address and other credentials from you WiFI chip on your phone...just saying.Overall...very good product. I just would have expected a better signal clamp.

Telefono da oltre 6,6" più custodia...? Qui c'entra...

I purchased for my cellphones and I placed each one in the bag and dialed w/ another and there was no signal. None. It can fit two phones and well made. My only regret was not buying several more for family members ---- it's no longer available on Amazon.

Cuando llevas tfno dentro de la funda no recibe ninguna llamada ni msgs ni notificaciones de ningún tipo, como si estuviera apagado. Realmente aísla de todo. Magnífica protección.

Cette cage de Faraday remplit exactement son rôle. La fermeture par aimant et velcros est efficace. Les velcros sont placés un peu haut et sont assez étroits. On a ajouté des velcros autocollants plus larges.

Did not block Bluetooth, and I continued to receive emails and messages that used WiFi. Appeared to block cell connectivity, but I don't have a lot of confidence that it does it well at this point.
