“This is now my 2nd BACtrack. Previous one was app only & didn't have the little screen on it.
I love this added feature! it makes it so much easier than having to pull phone out & connect everytime, while still getting the advantage of the Zeroline feature telling how long til sober.
It works well everytime & is ready to use in normally 5 seconds, which is super handy.
Definitely have to wait 15 minutes though to ensure getting an accurate read.”
