“This is the best choice for police grade accuracy. Not only did I buy a new one, but sent my older one in for calibration to have an accurate one in each car.”
“I bought a BACtrack because I drink socially. The ease of access to use the app on the phone and store history is one of my favorite features of this device. I previously owned a BAC Trace but there was no phone integration. I decided to go ahead and upgrade to this newer device because of the phone integration. I also recommend ordering a case to carry it because you can hold more mouth pieces in it and protect it.”
