First test Friday night after drinking just two (small) and a half glasses of wine during a meal (plentiful) restaurant. Result of measurement approximately 45 minutes after the end of the meal: 0.60 grams per liter of blood ;. the rate seems very high but it is possible. 35 minutes later the rate drops to 0.50. Always possible. But 45 minutes later the rate is equal to 0.000. Despite several attempts to reset (as advised in the instructions) the rate consistently remains at zero.
New attempt last night. Two glasses of champagne as an aperitif and two glasses of wine during the meal. Control 45 minutes after the end of the meal. Result: 0.00
I make SEVERAL attempted reset, turning on and off several times the unit. It gives me every time a zero measurement.
I have serious doubt on the reliability of the measurements made with this unit.
