## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    phMakes me feel more secure from identity theft.
  

*by D***E on Reviewed in the United States 🇺🇸 on January 30, 2019*

Received these two bags yesterday.  I tested my cell phone after putting in bag and called it from landline.  It blocked call and didn't ring.  My phone is a 5.5" Samsung, and it's a tight fit, but adds padded protection for phone.  Holds credit cards and money.  Hoping the protection continues to work to keep anyone from trying to steal my identity.  So far, so good.

### ⭐⭐⭐⭐⭐ 







  
  
    Good product for a great price.
  

*by B***M on Reviewed in the United States 🇺🇸 on May 7, 2019*

I bought this to keep my car keys in when at home. I just purchased a new volvo with keyless ignition and have been reading about an increase in car thefts by criminals with high tech devices that copy your key signal through your walls. To test this pouch I tried unlocking my car while the key was inside the pouch and was unable to. So I assume it is doing its job. The price was great and the fact that you get two pouches made it even better. I actually ended up using the 2nd one to carry our passports while on a recent vacation to keep them safe from identity theft scanners.

### ⭐⭐⭐ 







  
  
    Nice size, well made, not sure it’s working properly
  

*by N***S on Reviewed in the United States 🇺🇸 on March 28, 2019*

Is this bag also supposed to block incoming emails and texts? It doesn’t and I had the phone in the proper pocket with the microphone turned on. Other than that the size is perfect, it looks nice, I can put it in my pocket and I like it very much. I’m using it to stymie a stalker who I believe was using GPS on my phone to track me. I haven’t seen him on my walks since I got this bag. The phone also rings inside the bag when there’s an incoming call.
