Reviews: GPS Signal Jammer + RF Signal Blocker + Cellular Jammer

recommend rating

I’ve bought it to protect my car alarm from unauthorized use. I’ve heard that there are a lot of car thieves that can use my own security alarm against me. So now that jammer is my security measure. It’s cool, but antennas are rather long and inconvenient. I don’t know whether it is possible to make them shorter, but it’s ok for me.
