SamfolkSamfolk Faraday Box with Faraday Bags for Car Keys, Car Key Signal Blocking Box, Keyless Entry Car Key Safe Protector Car Alarm Anti-Theft Shielding Cage

I've tested this Faraday box, and it effectively isolates a mobile phone from electronic communications. Add a small white-noise Portable Sound Machine to the box with the mobile phone for good measure (both the small machine and a large mobile phone fit in the large-size box), turn on the machine, close the lid, and you can have a private in-person conversation with zero possibility of surveillance via the mobile phone.Do I also wear a tinfoil hat? No, but the desktop computer on which I'm typing this review has no built-in camera or microphone, and I physically disconnect my external camera/microphone from the computer when not in use. Nor do I keep any super convenient, voice-activated devices in this room. This is because I care about privacy, and my impression is that most technology companies don't.Do I go to the trouble of isolating my mobile phone very often? No, I'm lazy about that. But I want the ability to have an in-person conversation (or rehearse a presentation or talk to myself or pray out loud) in reliable privacy if and when I feel it's worth the trouble.If you think putting your mobile phone in your closet, under your mattress, deep in a drawer, or in an adjoining bathroom with the door closed is enough to prevent its use as a listening device, you might try getting on the phone with someone, putting your phone in those places, speaking at a normal volume, and asking the person on the other end how much they could still hear. It's an eye- (or ear-) opening experiment.I also recommend keeping any mobile phone's operating system and apps up to date and restarting it on a regular basis.

Don’t think! Just get it now. I’m a techi person, I was very sceptic. When my box arrived, I locked my Lexus key fob in this box, walked over to my vehicle and so far, no lights, blinks, or clunks happened. The car did not come alive when I placed the closed box holding my key fob next to my driver door handle. I pulled the handle and it remained locked as if I was invisible. As soon as I opened the box, the Lexus woke up and I was able to open my door. This was very entertaining. From there on, I made a new law in my house. Everyone with keys and RFID devices will keep them closed in this awesome box at all times. Just for a cherry on top, our vehicles no longer go into panic mode at random anymore.

★★★★★ Works Exactly as Promised — No Issues with Key Fob in the PouchThis product works exactly as advertised. I’ve seen some reviews claiming that the key fob doesn’t work properly while stored in the pouch—but that was not my experience at all. The Faraday protection is excellent, and my key fob is completely blocked when placed inside the pouch.Maybe others received a defective item, but the one I got works flawlessly. The material is solid, and the signal blocking is instant. In my opinion, it deserves the five-star review I gave it. Highly recommended.

Box works as described. Put keys in, closed & latched box and their signals were blocked.Good value for the money. Box lid does not completely open, and I suspect forcing it would damage box and/or shielding. That said, it opens far enough to easily put your key fobs in and to get them back out.Have not tried included key pouch.Again, good value for the money. Get one and protect your fobs from cloning and hence your car from this type of theft, which in my area is on the rise.

The box has always worked fine, no problem. But the pouch: I rated these pouches 5 stars but with a warning to buyers: THEY STOP WORKING AFTER ABOUT YEAR. You need to periodically check the ability of the pouch to block the signal. I have had two pouches stop working and what I did, after some research online, is to recreate a pouch out of aluminum foil and placed it the pouches. I used Gorilla tape to tape the opening and Gorilla 2 sided tape to stick to the inside. They both work fine and I didn’t have to reorder.

This box is just the right size to hold my entire key ring (which includes my FOB, several keys, a wrist strap, and a keychain or two) with room left over for 1 or 2 more sets of keys. I used the pouch it came with for my spare since I keep that in a different place and that doesn't have anything attached to it. I like the way it latches closed so it won't open if a child or pet knocks it over. Overall, I am satisfied with this purchase.

The Samfolk Faraday Box with Faraday Bags is both functional and attractive. It effectively blocks signals, giving me peace of mind that my car keys are protected from theft. The included bags are a great bonus, and the box itself looks sleek on my entryway table. Highly recommend for anyone looking to boost their vehicle security in style!

This faraday box (and probably all others based on photos) has a design flaw. Based on using a faraday testing app on my phone, I found that a lack of shielding on the lip of the lid causes a failed test unless weight is put on the lid to force the upper/lower shielding material to make electrical contact. Adding aluminum tape to completely shield the gap solved the design issue.
