  1. Andrea Pickard

    Simple to operate, durable, easy to carry in your pocket or briefcase. Nice way to help mask private conversations on the go.

  2. Asif Iqbal

    I wasn’t aware that the noise it emitted was so loud. It is difficult to talk over but I am confident that it does work.

  3. Patrick J

    The audio jammer is a great buy to mask audio from spy devices nearby. I like the product, thanks.

  4. Jammer-Store

    This min audio jammer device can be adjusted from a soft white noise sound very loud by turning the dial. If I place it near the front door of my apartment, it drowns out the sound of my voice if I’m having a discussion that I don’t want anyone to hear because when I walk down the hall, I can hear personal conversations. And I live in a high end condo and expected that sounds would be more buffered. I place it near me when I have a private phone discussion that I don’t want my other family members to listen to. Assume that it will last a long time and that the technology that it’s made with is why the price is what it is.

  5. Ali Gamal

    this thing makes a bunch of noise, like a tv that isn’t getting a signal. Apparently this keeps microphones from listening. I only use it when having very sensitive conversations and I do not think I’m being recorded. It can be loud but it is well worth it.

  6. Fawn

    Excellent device!! It does what what you claim will be getting one more!!!
