Review 5 Bands Desktop Jammer
High-quality products, value for money! Ship and receive the item immediately! Will definitely buy again!
I lighted it up last night and also checked the coverage with my war driving app. And provide another measurement tool.
It work very well. Successfully blocked the phone signal around me!!!
Better than expected! I successfully shut up all the students' cell phones!
Very convenient and user-friendly design. All frequency bands can regulate the output power, can interfere with the signal according to the need
