It has been a while since I reviewed a BACtrack product, because I honestly don’t really need them. That is not a slam on the product, because I highly endorse any product that will save lives. There is a kind of poetic justice as I first reviewed a BACtrack product one year ago after CES 2014, and I now am working on reviewing another with the BACtrack Vio.

When I first saw this version on the BACtrack, it was being held in a spokesperson’s hand. I commented that it is so small that it could be put on a keychain. At this point, that spokesperson moved her finger and I saw the keychain.

Like its predecessor, the Vio connects to your iPhone or Android smartphone via Bluetooth. Then there is a flip-up mouthpiece to collect a quality breath sample, and it allows you to get a blood alcohol content (BAC) and even estimate when your BAC will return to zero. Using its BACtrack Companion App, you can track BAC results over time, including optional photos, notes, and drink logs. Yeah, you got those handy graphs that let you know if you have a problem, and the app will keep it private.

If you want to get in on this BACtrack Vio, you can get it for a lower price on the BACtrack site for $49.99.
