Reviews: Broad Spectrum Cell Phone Signal Jammer GSM/CDMA/3G

recommend rating

That portable GPS jammer is an easy and convenient way to get rid of GPS tracking. I'm using it because I've read that it is possible to track my location with my own smartphone, using built-in GPS receiver. But no one is able to do that while my jamming device is on, and the best thing here is that it never interferes with my mobile calls and mobile Internet! The only problem I've experienced with that device is a rather weak battery, but that was not a problem to replace it.
