Seeing the prices practiced by Jammer, 4G Cell Phone Jammer - jammer4uk
I can only think that the company that sells the devices to the Brazilian penal system is practicing exorbitant prices, or that those responsible for the purchases are stealing. Note that the price of the devices range from 99 to 600 dollars (200 to 1400 reais). A modicum of value to avoid the terror offered by the thugs to thousands of families by this country.
