Why are these signal jammers so popular?

Compared with early signal blockers, its interference capability has been improved from blocking only a single frequency band to 8 channels, covering the frequencies of commonly used equipment in daily life. Of course, it all depends on your own choice. You can select the frequencies you want to mute and leave the others unchanged. Because we design a DIP switch, it allows you to control the interference frequency according to your own wishes in a more personalized way. When all its switches are turned on, there is no doubt that its interference ability is the strongest at this time.

The use location is not limited to indoors. You can easily carry it outdoors when powered by batteries.

After a tiring day, you don’t want to be disturbed during your break. You can use this device with GPS navigation APP, spy devices, wireless devices, and other devices to create your perfect rest plan.
