LVFEIER security pouch - Cell Phone Anti-tracking Anti-spying GPS Rfid Signal Blocking Bag Shielding Pouch Wallet Case for Cell Phone Privacy Protection

This material is excellent at blocking EMF/RF waves, I put my phone inside while playing an online video and I used my RF meter (AcoustimeterAM10) to measure the activity and it totally blocked all communication of EMF/RF waves. My phone operates on the 2.4GHZ microwave band.

Very good product! Everything from this brand works very well. Eventually sometimes phone calls do come through if I have it in the folder but I can measure that no EMF comes through. Most of the time all signal is blocked and calls can't come through. But for me the most important part is that it blocks radiation when you're out and about.

Excellent, strong and nice looking. Friends like. Would buy for presents

Just ok

I feel safer from radiation put my phone in overnight hope it works hard to know

the pouch is easy to use and an alternative from flight mode

Absolutely HOPELESS . You need to take this out of production. .phone could receive calls/texts an emails once in pouch. . Just sent it back this morning .. supplier was very helpful in quick response

Purchased to reduced the EMFs emissions from mobile phone.
