    Very effective device for the protection of privacy. Convenient connection power supply via USB 5Vcc, very modest absorption, does its duty by respecting the technical characteristics stated by the manufacturer, convenient the metal container carefully treated inside with protective materials to preserve the equipment.

    Awesome little GPS jammer for a decent price, works fine from a powerbank too. If the power is insufficient the screen starts blinking so keep in mind that you need a stronger one. Shipment was fast and it was very well packaged.
