4G WiFi Desktop Blocker

AMAZING! I was ready tear out my landline due to the number of unsolicited calls wasting my time. Literally, within the first two days my cell phone jammer stopped over all of these aggravating calls. Now all I have to do is open this device from any extension in our home to eliminate the other unwanted callers. If you make a mistake in blocking someone, you can reverse it. I was a skeptic prior to purchasing, however, now I'M TRULY THRILLED WITH THE RESULTS which has reduced unnecessary stress, wasted time and aggravation in my life.
