BACtrack C8 Breathalyzer | Professional-Grade Accuracy | Optional Wireless Smartphone Connectivity | Compatible w/ Apple iPhone, Google & Samsung Android Devices | Apple HealthKit Integration

I am so satisfied. One thing I love about this device is, it works both with or without a smartphone. I strongly recommend it to anybody who enjoys spirits.

I love having this for mimosas at brunch and dinner and drinks. It helps me keep track of how I'm feeling and whether or not to cut myself off. Also the feature where you get to guess is nice too I guess right almost every time now because I'm used to how my body feels at certain BAC's. Overall I would highly recommend this it seems to be incredibly accurate and it's small enough to always have in my purse because you never know!

I use the product as a safety precausion since it´s sometimes hard to just by feel know if you are clean. This pocket size meter works like a dream

You simply never know when it is truly safe to drive by guessing. Never risk the consequences that can arise from driving while impaired. It takes less than 30 seconds to check in on the Bactrack. It fits easily in a pocket or purse and is easy to use even without the app. We use it ever time we plan to have a few drinks.

Very accurate and easy to use

Definitely recommend. Especially if you have an interlock in your vehicle and did drinking the night before.

Find that it's a good safety measure to have everyone have one. Those who are just starting to have adult beverages really don't sometimes think they've had to much. This at least keeps them in line and makes them more responsible adults.

Great for a night out when you know you'll be drinking. Those drinks sneak up on you and it's a relief to know what your BAC is and if it's too high, how long before you're able to drive again.

The concept is great, record your BAC and store it on your phone. But there are two modes, offline and online. Online needs your phone to be connected and offline doesn't have any sync with your phone - leading me to use the offline mode only and missing out on much of the data-storage fun this product advertises. Instead this device should work as offline-only, but store the readings and a timestamp, syncing with your phone periodically much like my watch does.

Love the device in its own BUT wish it had the associated application supporting the Android OS. Major disappointment it does not. Also would like an automated in device feature that indicates when it is close to time to ship off to have it recalibrated. Prefer that based on the device's actual need based on current condition or at least tracked usage versus a set timeline.
