Features: 1) No harm to mobile phones: this jammer only prevents mobile phones from transmitting or receiving signals only when they are in the jamming range. 2) Can function stably and continuously under various environments. 3) Green and environmentally friendly device, no harm to human and objects. 4) Rapid adapting: based on sensitivity status of each mobile phone, normally within over ten seconds after being turned on, the signals for all types of mobile phones will be disabled in the working range. And a couple of seconds after it being turned off, all the mobile phones will be back to normal again. https://www.jammerssl.com/product/desktop-8-antennas-2g-3g-4g-wifi-gps-lojack-signals-jammer/
