Review Cellphone Signal 3 Bands Blocker
This mobile WiFi blocker is very suitable for final exams. The cheaters don't know how to deal with themselves!
As powerful and versatile as I just expected
Very portable jammer! Shipments are also very fast
It is a very compact jammer. Can interfere with GPS and mobile phone signals at the same time, very convenient!
Very compact disruptor, can be carried in your pocket. Really convenient, the train does not have to be disturbed by the phone ring
