    I have compared it to my buddy who is a cop and the results have been accurate. Good buy. Need to try it out a couple times when you are sober so you know how to use it. Very simple to use.

    It shows the subtleties of recent adjustments. I blew a 0.00, did a mouthwash rinse, spiked high and steadily dropped as time passed. Batteries last a long time and hasn't yet needed recalibration.
