Hodufy Faraday Bag for Laptops (20 x 15 inches), Faraday Cage, Faraday Bags for Phones & Key Fobs, Fireproof & Water Resistant Bag, Anti-Theft Pouch, Anti-Hacking Case Blocker(Black)

I recently purchased the Hodufy Faraday Bag for Laptops (20 x 15 inches), and I am thoroughly impressed with its performance. This Faraday cage is an essential tool for anyone concerned about privacy and security.One of the first things I did was test its effectiveness by placing my phone inside and attempting to call it. To my delight, there wasn't even a single ring – it completely blocked the signal. This level of signal blocking assures me that my devices are secure from unwanted tracking or hacking attempts.The bag's size is perfect for laptops, phones, and keys, making it a versatile addition to my security gear. The material feels durable and well-made, giving me confidence that it will protect my devices effectively for a long time. The design is sleek and professional, suitable for both personal and professional use.In addition to its practical functionality, the Hodufy Faraday Bag is easy to use. The generous dimensions ensure that it comfortably fits my laptop and other electronic devices, while the secure closure keeps everything safely enclosed.

I work for the government, and we use faraday bags in our daily business. Well the ones that we ordered from our government supplier DO NOT WORK. So I set out to find a product that did, and could fit a laptop, and this is what I found. Well made, fits up to a laptop, or several cell phones and other electronic items and it BLOCKS ALL SIGNALS. We made several attempts to get any signals through the bag to no avail. So if you need a product that actually works, buy this. (do not consider this an endorsement from any government agency)

As soon as this was delivered, I put my cell phone inside it and called it from another,phone, no signal reached my phone. I then set my police scanner to run and it didn't get any signal, then did the same with my portable ham radio, same result. As soon as I can acquire an EMP device, I will test it and let you know the results

Udate to revise my comment. When double bagged it works great. I bought this Hodufy 20x11 bag in March 2023. It looks and feels good. The Velcro closer is strong. I have been storing a small laptop and my 2nd cell phone in it. Today, I pulled out the phone to charge it and update the software. Then I put it back in the bag. I found out that I left the phone on, in the bag, when it started ringing for a phone call (its link to my primary phone number). I then dial the phone from my primary. Yup, it rang inside the closed bag. Bottom line - The bag doesn't block cell signals. And if it can't block that, what else will it fail to block?

These are great! Compared to other brands, they are about the same, but their special feature is a hook on the side to let you be able to clip it onto something or inside a bag because these can be really small...if you get smaller sizes that is. They are waterproof, the velcro works, they're good, and pretty much the same (in my opinion) compared to others. However, others do not have that little hook on the side, which is why I choose these over others.

unlike everyone else who is trying to sell you something like 2 small keyfob faraday bags (which are a fearmonger product, i’ll explain later) for $10-$20 you should just get this big one for $20. i tested it with putting a bluetooth headset and a cell phone in it and it def tested true. no signals passed in or out that bag. as for its other claims (water and fire proof i believe) i have not tested those but fingers crossed hope that they aren’t lying. it has a dry oily feel to it. prob because of its material. it seems very well made. the stitching is of a higher quality than usual from china. i think you would be pleased to own one.edit- i forgot the part about to explain later… you don’t need a faraday bag for your key fob for your car. when they push that they are fearmongering. you can’t clone a key fob unless it’s being used. and if it’s being used it can’t be in a faraday bag otherwise it won’t work.

****MAIN TAKEAWAY: This looks like a great deal for faraday protection but it is a scam and is nothing more than a fabric pouch selling at a more expensive price than fabric container with Velcro.**** (Moved this to the top for those not wanting details. Continue reading for more)Purchased this bag to for some mobile electronic protection in a go bag. I ended up needing more capacity so I also purchased a combo pack from a competitor, which was also a bit more expensive.The competitor’s large pouch was exactly the same dimensions and looks exactly the same upon initial inspection. However, if you pick up each pouch, you can clearly hear a crinkling in the competitors pouch while this one is just floppy fabric.(For context: A faraday cage is made with a conductive material enclosing an area and devices inside are protected when separated by an insulator.)Because of this, the feeling of only fabric made me immediately skeptical. I started testing the bag and realized I could get cell signal and Bluetooth even with my phone inside. I folded the bag 5+ times just to ensure that it wasn’t a fluke. I linked up my Bluetooth headphones and could listen to crystal clear music while my phone was enclosed.I then tried the competitor’s bag (which made a crinkling noise). The second I sealed the bag, the signal immediately cut out. No bluetooth connection and no calls could be received.

This one works. I've tried quite a few of the bags on Amazon and some of them flat out dont work or work for a while and stop being effective. I tested GPS/Bluetooth/Wifi and Cellular with this bag using my phone and laptop and found it to be 100% effective, at least from the standpoint of using those technologies to get a useful signal. I cant speak to it's durability because I just bought it. The last test of a Mission darkness bag, by comparison, was useful for the first year and then eventually I could hear notifications going off through my bag as well as reciept notifications of connections to my VPN. I hope this one lasts a bit longer.
