Person 1: 6 tests with no result ( probably over limit after test 3 at 3 pints of Carlsberg last test at 6 pints still no result. Person 2: 6 tests with 3 over limit fairly accurate after test 3 with 3 pints of Stell Artois. Person 3: 6 tests random accuracy amber up to 1.25 bottles of red wine approx 13.5% two red and final one no result at 1.5 bottles. Guess who will be asking for his money back tomorrow, certainly won't be relying on it for the "morning after" check. Cheers
