The range of this jammer is really wide, it is enough for outdoor use, and the appearance is also my favorite.
Review Military Cell Phone GPS Jammers
The device is powerful and the interference range can reach 20m. I bought one and installed it in our meeting room. It really works well, and the boss is very grateful for it. This is a good product at a reasonable price, free but fast delivery, Best Buy! You can try!
The product is better than imagination, the design is perfect, and the portable jammer is easy to use for a long time. This is a common problem with portable jammers. Try to take a break after get off work to extend the life of the jammer. The jammer can block all frequency bands of GPS, which is very convenient.
When I started using this jammer, I finally understood why it has so much praise.
