How accurate are BACtrack breathalyzers?
BACtrack uses carefully-engineered technology to deliver reliable, consistent BAC results, with unparalleled accuracy. Several independent agencies have tested popular personal breathalyzer brands and found BACtrack to be the most accurate.
How often do BACtrack breathalyzers need to be calibrated?
Our general recommendation is to have your BACtrack calibrated every 12 months, but it really depends on how your BACtrack is performing. With proper care and usage, we’ve seen that our devices can go for 1000’s of tests before needing calibration.
Where are BACtrack breathalyzers made?
Our products are designed in our San Francisco headquarters and manufactured in our overseas facilities. We aim to provide the most accurate, reliable & affordable breathalyzers on the market, while delivering exceptional support to match.
What should I do if I’m having issues with my BACtrack breathalyzer?
In the rare instance where you are having trouble with your BACtrack, please send a message to our US-based customer success team directly from your Amazon orders page and they’ll be happy to help you troubleshoot.
Am I able to return my BACtrack breathalyzer if it stops working?
Yes, if your BACtrack ceases to function properly during the first year of operation, we will repair or replace the defective product at no additional charge to you.
