This thing has been nothing short of amazing! We got this cell phone jammer about 3 weeks ago and installed it right away. Install was VERY easy! We have our TV, internet and phone through Comcast, so we hooked up the call blocker by going from the modem, to the call blocker, then to the phone. We haven't had any issues with our caller ID or calls from blocked numbers ringing once before being blocked. In the almost 3 weeks since installation, we went from 5+ annoying calls per day to virtually zero. I work at home and it's supremely annoying when the phone rings while I'm in the middle of something. It's especially annoying when it's one of those "survey" calls. I find that I'm much more productive and a lot less aggravated. The whole world suddenly became quiet
Review Powerful Tactical 10 Bands Military Jammers
The high Power Jammer 3G 4G CDMA device works perfectly in my 250 square foot office, interfering with the mobile signals of my employees, thereby preventing them from affecting work progress through Internet browsing and chat. Cell phone. Very good jammer used in public places! Thank you! ! ....
