Question 1

Will these bags fit my modern phone if I keep my protective case on?

Accepted Answer

This is the most common feedback we see. The bags are designed for a snug, signal-blocking fit around the device itself. For most modern smartphones (like the iPhone 15 Pro or Samsung Galaxy S23/S24) with a *slim or medium case*, it will be a very tight fit. Bulky, heavy-duty cases (like OtterBox Defender) will likely need to be removed. If keeping your case on is essential, many Reddit users suggest looking for "XL" or "Tablet-sized" Faraday pouches.

Question 2

How can I be sure the bag is actually blocking all signals from my key fob or phone?

Accepted Answer

Great question! The best way is a simple at-home test. Place your device inside, seal the magnetic closure, and then try to call your phone, unlock your car from a short distance, or use a RFID/NFC scanner app. No signal should get through. Many TikTok reviewers show this test—if your device can still connect, the bag isn't working properly for that specific signal strength, and you should contact us.

Question 3

Is the bag truly waterproof, or just water-resistant?

Accepted Answer

We rate these bags as water-resistant, capable of protecting against splashes, rain, or brief exposure. However, they are not submersible or designed for swimming. Some user tests have shown that prolonged immersion or high-pressure water can penetrate the seal. For everyday protection from the elements, they perform well, but don't rely on them for underwater use.

Question 4

How durable is the magnetic closure and the material?

Accepted Answer

The bags are made from a durable, signal-blocking nylon fabric with strong neodymium magnets. For daily opening and closing, they are built to last. However, as noted in some long-term reviews, avoiding sharp pulls on the magnets or over-stuffing the pouch will extend its life. If you need industrial-grade durability for rough use, a hard-sided Faraday box might be a more suitable alternative.

Question 5

What's the best use case for this 2-pack? Who is it ideal for?

Accepted Answer

This set is perfect for anyone seeking affordable, reliable protection against digital theft and tracking for everyday carry. It's ideal for separating your car key fob (to prevent relay attacks) and your phone/credit cards into two bags. They are hugely popular with urban commuters, travelers wanting extra RFID security, and car owners concerned about keyless entry hacks. The value of the 2-pack is in this convenient separation.
