I encountered this stigma just last week and immediately tested it. It can really effectively block cell phone 3G, WiFi/Bluetooth and GPS signals. This is also very convenient because I can pinpoint one or two frequencies that need to be blocked. Big !

The shielding effect is good, and the concealment is good, very satisfied

The jammer provided by the seller is of good quality and can effectively block the above frequencies. A very trustworthy seller.

This is a sturdy, well-structured device that provides more coverage than expected. The side DIP switch feels good to the touch, because I don’t always need to turn on the GPS blocking function and turn it off.

The seller is very considerate and provides very professional advice on products and transportation. So far, the jammer has worked very well.
