A12 Powerful GPS Mobile Signal Jammers Comments

In my experience, the cell phone jammer does what it claims extremely well. My house was getting hammered with three or more solicitation calls every day in the late in the afternoon, dinner time or after dinner. My high quality cordless system blocks calls, but we ran of blocking capacity!! We could not block any more numbers using our cordless phone system. So we purchased a jamming device to hook it to our cordless phone system and it worked great. I won't waste my time on those calls again
