Oh my goodness, of course you can’t use an $39.99 Internet machine to determine TRUTH! I can’t believe someone actually thought that it was a link for one. Quite the contrary. Making life-altering decisions based on something so controversial and unsubstantiated as lie detection tests (no matter what they cost) bothers me, sorry.
Here is yet another example of the issues with the concept (it’s a really long article but this part is thought provoking) from this site:

As a psychologist professional for the past approximately 50 years, allow me to again get back to my own exposure to the practice of polygraphing for the purpose of detection of lying and deception. As mentioned earlier in this paper, my first, as an undergraduate student psychologist, I and a fellow student (i.e., S. T. Baker) conducted research that involved use of a Berkeley polygraph to measure anxiety changes as a function of exposure to English taboo words. We found reliable emotional changes to what appeared to be identifiable collections of such word stimuli.
For example, we found one subject to seemingly reliably show some emotional changes when presented with and asked to orally repeat words that we identified as having some association with dermal (i.e., skin) matters. He showed increased anxiety when involved with words such as itch, rash, scab, and scratch, etc.. Another subject was observed to show increased anxiety when involved with words that described seldom exposed body parts, such as breast, belly button, butt, and genitals. Other subjects appeared to show increased anxiety when exposed to other word category collections. Nothing in this long-ago conducted experiment was involving lying or deception, as far as well could tell and were aware of.
This research did though suggest that persons can and do react emotionally when exposed and involved with individual words and concepts . The act of lying and of attempting to deceive may have absolutely no connection, whatsoever with emotional changes that are detectable using the polygraph technique.
Major causation may simply be emotional reaction to certain words and concepts. William Safire had some interesting things to say in an New York Times article entitled
Lying “Lie detectors". You can access it here:

Whatever you do, you do want to make an informed decision about what it means to put all your eggs in a basket such as this….it’s not as cut and dry as one might think. Good luck!
