I received the jammer and it even arrived two days earlier than expected. After testing, the effect is better than expected. The fan is a bit bigger than I expected, but I am satisfied with everything.;

I want to thank the company for its excellent service. I asked many questions and answered them all. My portable device broke down, and I was quickly picked up and returned to duty. I blocked those who needed it, I bought 4 different items from the company and everything was fine. thank you very much.

As shown, it can shield a distance of 40-50 meters, a very good mobile phone jammer, and it is also very good to shield other signals. Trusted jammer shop.

The concealment of this jammer is really very good. In order to prevent children at home from surfing the Internet too much, it is really a good device. I like this product very much.
