Portable Cell Phone +GPS Signal Blocker with AC/Car Chargers from China shop

This portable GPS and cell phone jammer can keep you from being tracked by GPS and cell phone signal tracking systems. It is also good for schools, churches, conference rooms, hospitals and any other place that cell phones may be cause a distraction or interference.
As an engineering student I can say you that it will be cheaper ONLY if you will make something similar by yourself) But it is quite difficult to do it by yourself, believe me, I know. So if you want some silence near you, just buy it!
