I received this jammer yesterday and make a real test. In the car it jammed my satellite radio signal and cell phones in neighboring cars. In the mall it interrupted everyone's cell phone in a large radius more than 10 meters. I took it to a meeting. It not only blocked everyone's cell phone, but did not knock out the WiFi that was being used in a presentation,coz there are four switch to control different signal. I need not to shut it off. It is very powerful transmitter. You don't worry it will be very hot if you carry it in your pocket,for there are a cooling fan. It's the best to keep it out where it can be ventilated. Don't tell anyone when you are using it, not even your spouse. In a restaurant or a theater it keeps the Bozos under control. Date Added: 05/09/2015 by Edith Saporito
