Quickly test your BAC levels with this BACtrack BT-M5 mobile breathalyzer, which is compatible with most Bluetooth-enabled iPhone and Android 4.3 or later smartphones and features police-grade Xtend sensor technology to ensure accurate readings.
Unit is very easy to use, phone only needs to have Bluetooth. App immediately recognized device and connected to it with no pairing or anything required. Unit is very accurate and will return the same result to an accuracy of .001 when I tried consecutive readings. The app requires a specific version of android so be sure to check compatibility before purchasing. Great product, would recommend.
