Note:

1.First of all, the machine is preheating in the first 10 seconds after it is turned on and cannot be detected. After the first 10-second countdown ends and the second 10-second countdown begins, the air blowing test can be successful. Incorrect usage, please try to use again. How-to videos are in the product link.

2.It takes at least 20 minutes for alcohol to be absorbed from the digestive system into the blood system. So it is recommended to test 20 minutes after drinking.

3. Please do not directly wipe the product with chemicals or corrosive solvents to prevent liquid from flowing into the blowing hole.

4. If tested under low battery conditions, there will be a certain deviation between the test value and the actual value.
