RF Anti-Radiation Signal Blocker Bag for Cell Phones - Brown

Pros: Does what it says, put your phone inside this bag, and it won't be able to recieve any phone calls. Useful when you need to get into a short meeting and don't wanna be disturb (It's a very good option if your phone type need a long time to boot after being switched off) The size is quite perfect, can fit in a blackberry and most types of phone

Cons: A very plain and design

Other: 3 bucks can save you a lot of boot time trouble!

Pros: This mobile phone pouch works as Faraday Cage, so any electronic device can not communicate. This includes mobile phones, trackers, etc. It is a good thing for phones like iPhone, where you can not take out the battery from the device.

Cons: After some time of intense use the "leather" can get damaged, but it is normal as the price is very low.

Other: This is a great and reasonably priced tool for protecting your privacy. There is no other protection for mobile phones with built-in battery.

Pros: It really works just like the overview says! I use it for my smartphone and credit cards! Thieves are not able to scan my credit cards or Banking cards' chips in my purse or bag!!

Cons: For 3 dollars I really can't think anything bad about it, maybe the color?

Other: It is better, easier and prettier than using a piece of tin foil to wrap inside of your wallet for protecting cards.
