Are people really telling you the truth? Find out with this Portable Voice Stress Analyzer. According to the product website, the device measures micro tremors in the voice to determine whether or not the subject in question is lying. An easy to read LED layout makes determining innocence or guilt quick and easy. Plus, it is small enough to put in a bag or briefcase, so you can falsely accuse and alienate your friends anytime, anywhere.
