    I decided to buy because it was Nigerian and I got an excellent product. I was so impressed.

  2. Rated 5 out of 5


    The best thing about this is the price. I got interested in their two-way radio after an AD on twitter. I tried purchasing but immediately I saw this jammer I was wowed and couldn’t believe the price for such large channel . I tried contacting a sales rep but the company’s CEO himself replied me. He’s got a nice personality and humor. I concluded to get the jammer alone because I couldn’t afford both the two-way radio and jammer at the same time. It works perfectly for me.
    Good product and a great customer service.
