I was thrilled to get this but figured I'd test it a few times to see if it works. My first test. I connected to a Bluetooth music receiver , I let the music play and then put my phone into this bag. The music stopped. 2nd test.. I had wifi turned off and data turned on, I put phone into bag and sent a text to my phone via pc. No sounds of receiving a text. I took phone out of bag and a few seconds later the text arrived! So far so good. I then turned off data and turned on wifi and repeated the previous test. Worked great!
Review WF-K6 Hidden Military SM 3G 4G GPS WiFi Signal Jammer
I purchased this to test in our secure facility. It blocks cell, Bluetooth and RFID from my initial tests. Now here's the very good part. Cell signals are easier to block, but Wifi is much harder, especially near the router. The signal strength can be very high. This device blocks both 2.4GHz and 5GHz Wifi. I'm recommending this to the higher ups, especially since staff can add a business card in the back Velcro sleeve.
Very cool jammer!!! It can be fixed to the arm. Although transit had an accident, but was impressed with the product.
