## Questions & Answers

**Q: What is the range? Like the cutoff, or high it goes?**
A: Hi Destiny,
The BACtrack keychain measures a range from 0.000 - 0.400% BAC.

**Q: how accurate are these.  eg  97%  85%  or whatever?**
A: accurate i used mine after a night out & it saved me rather than blowing into my car.

**Q: How many tests can you do?   Does it have to be recalibrated after so many tests?**
A: Hello,

Thank you for contacting BACtrack Customer Support. The calibration service helps ensure the unit is working within specification and providing accurate results. There is a general recommendation of around 200 tests or once per year before sending this unit to be serviced. You would place a calibration order online on our website and then receive an email containing instructions on where to send the unit to be serviced. Please contact our customer support center at (415) 693-9756 for more information or assistance with placing a calibration order. 

Best,
John Olson
BACtrack Customer Support

**Q: Does it come with disposable breath attachments**
A: Yes, this comes with three mouthpiece covers. However, they are washable and reusable, so you do not need to dispose of them after one use. Additionally, the device will work without the mouth piece covers, as there is a fold out  mouthpiece for you to breathe into during the test. The covers are more for sanitary reasons when sharing your BACtrack with others.
