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.;

This is a very good unit and it feels good. The cooling fan works normally. You need to put a large pocket on the jacket, or you can use the included carrying bag to put it on the belt

Jammers are very convenient and can interfere with various frequency bands. And turn on or turn off the corresponding frequency band according to your needs. The only disadvantage is that the frequency band switching is too small

This is a sturdy, well-structured device with much more coverage than expected. The side DIP switch feels good to the touch, because I don’t always need to turn on the GPS blocking function and turn it off

It just took about two weeks to arrive, which is not bad because it does not have a tracking number from China, but I am glad it arrived in packaged form. The bubble burst, and the workers tested in their homes ten meters away to restore their happiness.

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.

It's really a good shop, it can work for a long time, it fully meets my requirements, and the jammer is as far away as shown.

This is a relatively complete jammer product. The 16 frequency bands basically cover the signals needed in daily life. I am very satisfied with this shopping.

This is a very cost-effective jammer device that can shield the latest 5g signal, and the effect is also very good, it is very worth starting.

This jammer is really small. I will put it in my bag every time I go to and from get off work. When I need it, I turn it on. The shielding effect is also good, and all the signals around me are cut off.
