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

This thing works well indoors. It works well in restaurants, but sometimes it takes a minute to eliminate the signal. An office worker stammered outside with his mobile phone for 20 minutes, and I decided it was time to go back. Turn it on, she was ten yards away, and killed her phone in just a few seconds.

What a progress! I have used the portable model for a while and upgraded to that model when I saw it because the laptop is still running. The device not only keeps cool, but also has a better range. Thank you!

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.

This is a sturdy, well-structured device that provides 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.

high quality! I used it for two weeks and found that as long as there is electricity, the jammer can work for a long time. Highly recommended, the price is indeed very cheap.
