Accurate and Can Save Lives!
I once was a juror on a drunken driving case and the judge actually said, "I want to make it clear.  It is not illegal to drink and drive; it is illegal to drive drunk or impaired".  Well, it doesn't take much alcohol to get you legally drunk or impaired.<br /><br />This tiny little device (2" X 3" X 0.5") is a complex breathalyzer that uses your iPhone for results!  It only takes less than a minute to `pair' with your iPhone (you must download the free BACtrack app.  It will ask for credit card info, but is not charged).<br />First thing to do is set the settings to your gender and weight for accuracy.  Note that females have fewer enzymes to break down alcohol and certain races have even less.  Check Wikipedia or GOOGLE for this information.<br /><br />Open the app, and when it says `take a reading', a clock appears and gives you one minute to prepare.  Simply `BLOW NOW!' by taking a steady deep blow into the analyzer while watching the eight blue bars fill up - then you stop.  There is a slight `click'.  The test results are shown on your phone via a large number, such as 0.004 (which means it is likely you are very sober).  Click 'OK' and you are shown a `graph' that indicate the times between `blows' and your alcohol level.  0.08 is legally drunk and you should test again in fifteen minutes.<br /><br />There is also an option to get a "Dose-Specific Effect" of your alcohol level with suggestions.  It is also very important to wait at least fifteen (15) minutes to test after your last drink, cigarette or food consumption.<br />You can `tag' a drink for future use in the computer storage, like a beer, glass of wine, liquor, etc.  You can add a photo of that time period (although this would be more appropriate if you were at a party sharing the device and getting a shot of a 0.18% drinker looks like.  The device does come with three plastic washable mouthpieces.  There is a tab for notes.  There is also a `share' button which lets you share your results on Facebook, text it, or tweet it.  Now come on!  Close out the program and your entire previous tests are stored.  There is a system called `Zeroline' which estimates how long it will take your Blood Alcohol Content (BAC) to return to 0.00% based on your last test result.<br /><br />My results the first time:<br />I enter `Male' and `195 pounds' at 8:00pm on an empty stomach; 4 ounces; Vodka with soda.  This is a typical bar mix.<br />After one hour my BAC was 0.10.  Over the legal limit.  The second hour I drank a 2 oz. drink and waited an hour.  My BAC was 0.065.<br /><br />So 6 ounces of vodka on a fairly empty stomach with the `time to sobriety' (0.00%) would happen around 2:00am. This was interesting information.  It's a pricey unit, but not anywhere near the over $10,000 it is estimated, to deal with being busted drunk driving.  Drive safely!
