Why should I buy the Q.E.D.® Saliva Alcohol Test if I need an Evidential Breath Testing (EBT) to confirm positive test results?

The Q.E.D.® test is much less expensive to operate than a breath test.  The exception to this being if you conduct a very high volume of tests in a central location. By and large, each test done on saliva instead of breath saves money. Plus, performing two independent tests is more legally defensible.
