Faraday Bag for Tablets (15 x 10 inches)

Fantastic! This bag, when sealed up all the way (with the velcro), effectively blocks wifi and cellular signals, from our testing. Be sure to fold and seal it up, though; if it's not folded and sealed, signal WILL leak, as with any bag of this style. We were able to actually fit *two* 13" mac laptops in this bag at the same time (a 13" M1 pro and a 13" air), and still fold and seal the bag. We were very happy to find such a well-made, minimalist bag at such a great price point.

Quality material. Effective shielding

I have tested this bag under various conditions using my mobile phone and a electromagnetic field meter. My first experiments indicate works well blocking mobile phone radio links, and even blocks well WiFi radio links at very short distance ( ~ 1 m from a router's with multiple antennas) . However, it is important to understand, that the faraday bag only works well when the velcro seal is completely closed, if there is a gap in that seal, even small, the bag will not block all RF. If you are unhappy with the signal attenuation that the bag provides, use two of them, one inserted inside the other, check both are properly sealed, or use a metallic sealable bag inside the main bag to further block RF links. You can also fold the larger bag in half, to increase the line of sight shield between external antennas and that of the mobile phone, RFID chip or tablet, you are trying to isolate. RF shielding is an incremental process. Multiple layers increase effectivity of a Faraday Shield.

Pensé que fuera algo mejor

This fit my iPad perfectly. Well made construction.

Good Product

Unfortunately, this bag simply doesn't work. It has a number of flaws that render it basically an expensive plastic bag. This faraday bag has a single folding seal, effective Faraday bags have a double folding seal over the opening i.e. fold over and seal the flap to close the bag and then fold that seal over once more and secure it to insure the opening is completely sealed from any RF Energy. The effectiveness of this bag (or anything claiming to offer faraday protection) can easily be tested. Place a cell phone in the bag with the ringer turned up enough you can hear it through the bag, close the bag according to its directions and then call the phone. If it rings the bag is not effectively blocking RF energy from reaching the phone. Even doing the double closure manually on this bag made no difference as the RF blocking faraday “fabric” is not well made and thus not effective in blocking the signals / energy that can destroy your devices. If you really want to protect your electronics, the bag or enclosure needs to prevent RF energy (signals) from getting to the item you are trying to protect (this is a simple example, it is far more technical discussion than this forum permits). In comparison, one can get better protection by putting their device in a sock and wrapping it in aluminum foil than this bag provides. Maybe the best use for this bag might be putting your aluminum wrapped device(s) inside so it looks nicer than carrying around a big chunk of aluminum foil ;)

My sister wanted this for Christmas she loves it

The bag works! It blocked a signal to my cell phone. Its well made and the velcro is strong. Thank you! It does exactly what it was meant to do!

Excelente bolso para resguardar documentos, billetes, materiales duraderos resistentes, la recomiendo ampliamente

Great isolation bag, shields iPad from hacking, tracking and EMF radiation. Highly recommend to guarantee privacy, whenever not using electronics like iPAD or cell phone. Works great.

Listo.

Tested & these bags doesn't allow cell phone or key fob signals transmissions. Very pleased with size & quality for the price.
