Delivery was very fast. Customer service is very good.

I am very happy with the look, very nice device!

The merchant told me that the Portable GPS Jammer can only interfere with some low-end trackers and GPS devices that use GPS L1 signals. This is indeed the case, so buy carefully. It is recommended to confirm the frequency you need to interfere with before buying.

The device works well in my car, preventing others from locating my whereabouts.

Very nice device, I like it.
