  1. Aztlanteca


    This tool is invaluable and important. Recently 2 people close to me were diagnosed with cancer. In today’s environment we are constantly exposed to many harmful substances, entities, and signals. I use this a lot. So far nothing has peaked high in radiation. I have kids and a great family. Thankfully nothing to be concerned about has been detected including at work in my finish construction job.

    ✔ Yes, I recommend this product.

  2. MIMC


    Fluke/Amprobe no longer supports, services or calibrates. Very disappointed because its only a little over a year old. Worked great but as a medical center or business you have to make certain your test instruments are periodically calibrated.

    ✘ No, I do not recommend this product
