Bought this for my husband. He loves gadgets and this is a good one. It's so fast and easy to use. We use it every time we go out and have a drink or two to decide who drives home.
If you use BACtrack regularly for a while you will get a much clearer understanding of what a given BAC FEELS like. This will help you make better decisions about your drinking.
Purchased for possible use in a college honors course. Easy to sync, and use with iphone. Now trying to weigh the implications of using this device in an academic environment.
I bought mine, before the Christmas holidays last year and it was the best decision ever. All the different occasions where alcohol and having to drive are involved I have it with me. Friends get a kick out of it too. But the accuracy and always knowing your BAC is essential for someone who likes to enjoy a drink but doesn't want to take chances
