Faraday Bag for Laptops & Tablets & Car Keys - 3 Pack Faraday Cage with Reflective Strip, Faraday Key Fob Protector, Fireproof & Waterproof RFID Bag

Like other reviewers mentioned. There is some oily chemical on the surface of the bags which I really don't like and cannot tolerate. So I ended up giving the bags to others free.It does block cell phone signals (4G, not sure about 5G) only if the bags are completely closed as instruction said.But I don't think these bags can block all kind of signals.Since these bags work as advertised, so I give these bags 4 stars. One star is deducted because of the oily chemicals which made the bags useless for me.

This product does indeed block the signal so your devices can't be tracked but I did notice the recorder still picked up audio whilst inside the bag. This means that hackers are likely able to still eavesdrop through the devices even though the signal is blocked???

Great product but the small one could be just a bit bigger. My phones doesn’t fi. Please take in consideration that a lot of phones have cases. It’s too small.Thank you

Very nice and great quality!

This trio is a great find for its price, usefulness, and quality! I have peace of mind now about protection for my personal tech devices.

Got these for items to protect from EMP.

Great for those who travel frequently.

Bags seem to be made of quality material with a rubberized exterior I used my cell phone tablet and laptop and set them next to my 5G router and no signal would get through any of them it's a good feeling to know your electronics are protected
