Test lab notes

The mi­cro Usb-charged unit re­quires a smart­phone to op­er­ate, so don’t run your bat­tery down while you’re out drink­ing. The app is well-de­signed with an easy-to-use in­ter­face and nice fea­tures like a trend line that will pre­dict when you’ll be able to safely drive as well as di­rect links to Über so you can call a car if you can’t wait.

Per­for­mance: The Bac­track was the most ac­cu­rate of any of the units, read­ing only .001 off at the first sam­ple, dead-on at the sec­ond, .004 high at the third, .003 low at the fourth (.087), and then read­ing .01 low as the sub­ject’s blood-al­co­hol level rose well above the le­gal limit at the fifth sam­ple (.149). Be­cause it was ac­cept­ably ac­cu­rate through the le­gal limit where we would cease driv­ing, we do rec­om­mend it.
