Mini Portable Cell Phone Jammer

due to the overwhelming questions i got this from just search for cell phone jammer. This is a portable signal Jammer . It can block any GSM cell phone signal at a distance of 2-10m (radius) within which cell phone cannot be called in or called out, protecting confidential information from being leaking out and keeping away from the hazard caused by illegal usage of cell phone. And it won’t interfere with other devices within the range.
