Hi Paul,
Thank you for your feedback.
Your unit was returned recently for an inspection and based on the report, we found no issues with your unit. The unit was reading within the accuracy range during the test that was conducted.
We understand that you're concerned about your reading based on how you've felt your condition was in.
An individual's BAC varies based on multiple factors such as your body weight, metabolic rate and alcohol tolerance. Also note that an individual's BAC continues to climb for up to 2 hours after their last drink. We recommend testing yourself at intervals whereby allowing a 15-20 minutes wait time in between each test and testing yourself at least 3-4 times to have a better estimate of your BAC.
If you still have concerns regarding your breathalyser, kindly email us at support@andatech.com.au and our customer service team will assist you further.
