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

These faraday bags work great and my iPhone 13 Pro (with case) fits snugly inside. Larger phones with thick cases will probably not fit completely in these bags. So be sure to double check compatibility with your device.The blocking works really well, but isn't instant. It seems like it takes the phone a few seconds to realize it's disconnected. It also takes the phone a few seconds to reconnect once the device is removed from the bag. I don't think any of that is an issue though. Just something I've noticed.When I remove my phone from the bag the cellular connection shows that it is disconnected and reconnects after a few moments. Any calls made to my phone (while it's in the bag) go straight to voicemail and do not ring. Any GPS data is also paused and lost while the phone is in the bag. The key ring loop is a nice touch. I added a locking carabiner to attach the bag to a backpack. Very happy with the function of these faraday bags.

Great size and really works

Workable but does not allow much width at the bottom making it more difficult to seal certain items.

I was skeptical about this being full-proof or working at all, but my skepticism was dispelled after I received the product and being able to test it out for myself.I personally purchased this product to store my car's key fobs in to prevent parasitic drain on my car's battery since I don't drive it often, and was surprised to discover by accident that I the keys' signal still reached my car/was able to (un)lock it from my room where I store them - despite that my car is kept in the garage, and my room is on the second floor of a fairly large house and on the farthest side of the house/diagonally opposite from the garage.I tested both my main and spare key fob from my room, and confirmed that I was able to (un)lock the car. I then put the key fobs individually in the faraday bag while standing at the same point for the first test; I wasn't sure if the bag would work since I had to leave the top of the bag open/unsecured in order to use the key fob from inside of it. I was happily surprised to discover that using the key fob from inside the bag did indeed block the signal, and I was not able to (un)lock my car when testing it and re-testing it for assurance of my results.The price for this two pack is great, and despite the cheaper cost I think the material choice for the bag (I purchased the faux carbon and red stitching) does look elegant, and as a bonus matches much of the same faux carbon and red stitching on the interior of my car. I am using one of these pouches to store my key fobs in, and I will keep the other in my car's glove compartment or in my sling bag that I utilize daily as a bonus/peace of mind if I ever feel the need to place my cell phone within it throughout the day for added privacy.My only regret is that I didn't purchase this sooner as I had been on-the-fence about it for a few months due to my own skepticism. If you've been on the fence about purchasing this product - go for it! I don't think you'll be disappointed, and I hope that this review is helpful to those who have been hesitant to make this purchase.

Wanted to secure my devices and these easily protected my S25 Ultra with a case on it. Completely blocked all reception. Calls to the phone went straight to voicemail and connection to all Bluetooth accessories was lost.

Bought twice, so I could give one away. We might not be able to use our phones right away in an emergency, but we'll each have one with full memory for whatever it can be used for. Have a phone and full charger in each bag.

Had it completely sealed. Velcro closed tight and phone still beeped for texts and rang for calls.

Too small for my cellphone. Sadly, I ended up tossing both of them. It was hard to get my phone out of it.
