Customers are saying

Customers commend the Vio Smartphone Keychain Breathalyzer for its ease of use and compact size, describing it as "working great" and "quite accurate for a small Bluetooth device." However, concerns are raised regarding its accuracy, with some users expressing skepticism about its reliability compared to professional breathalyzers used by law enforcement. Additionally, the battery life of the device has been criticized for draining quicker than desired.

    Too good to be true pricing

    I bought as a deal of the day for about 30 bucks. It seemed like a neat novelty. But I could never get it to connect to blue tooth. As I researched the issue, it appears this is a common problem. I had thrown our the packaging, so just I ate the 30 clearance price as lesson in too good to be true pricing. There was a reason.

    I was sad that this was not accurate. I had a friend blow twice the first night we got it. First time was barley drinking and blew a .14 then had him blow later in the night when he was very very intoxicated and showed him still at a .14. No way he was at the same then as he was earlier. Waited the 20 minutes since last drink and followed all of the directions. Returned it the next day.

    Great for a party or oneself to recognize how little it takes to be over a legal limit.

    Definitely one of the smartest purchases I have made. You can connect the device to your phone via Bluetooth and use the application associated to the device in order to log your approximately BAC. It is a good way to make sure you are safe to drive after sobering up.

    All you have to do is download app and turn on app, Bluetooth and BacTrack. It immediately connects, which i was surprise how quick it was(5 seconds?) Used it about 8 times, testing after 1 beer, 2 beers...and wife tested...to see if it looks accurate. I think its pretty close. For a big guy like me 3 beers in just over 1.5 hours i blew .05...I think i would be closer to .08 or so. but eye opening to see it doesn't take much to be legally drunk...Nice feature to 'guess' your BAC and it also keeps track of how many drinks you have when you blow. Cant comment on battery life, but 1 AAA will not be a problem replace.
