      Eye-opening to what my BAC actually is!

      Posted

      Not only is this thing really fun to use when I'm out drinking with my friends (everyone wants to see what their BAC is), it actually has made me a much more responsible drinker. Prior to getting my BACtrack, if I felt fine, and I only had to drive a short distance home, I drove - even though I knew I was probably over .08. Now, I literally haven't gotten in a car after having more than a drink or two because I have a number staring me in the face, reminding me to not be an idiot for the sake of convenience. I also realized that, for the most part, I really had no idea what my BAC actually was (and neither did my friends). We all continually guessed lower, which was a bit scary - we all consistently thought we were in better shape than we were. The "Guess Your BAC" function on the app, while seemingly kind of trivial and game-like, has actually really helped me better gauge my BAC level. Highly recommended for anyone with a lot to lose from getting a DUI (read: anyone who drinks and owns a vehicle). Trust me, your BAC is actually probably higher than you think. Use a breathalyzer to keep yourself out of trouble.

      Novelty not 10% reliable

      First off there are plenty of reviews on this item all over the itnernet. I use this with friends more as a novelty thing when we are out together or whatever. If you use this thing multiple times in a row it will spit out drastically different readings. I tried it last night and it said i was .009 then told me 2 minutes later i was 0.00, then .004 then .000? Not ayt all accurate i wouldnt rely on this thing to tell me not to drive somewhere if i had event he slightest bit of alcohol. I just dont drive if i even have a drop of alcohol a DUI is not worth losing your job, money, family issues and more. Possibly even worse killing someone even if its an accident that you didnt cause and your involved they will check you and if you register anything on their accurate BAC testers you will get hit with DWI or DUI. The moral of my review DO NOT RELY ON THE READINGS FROM THIS THING!! Its all over the place.

      Works with Samsung S5

      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.

      Not accurate and a hassle to set up

      Posted
      anthonys2r

      Setting this up with my samsung phone was a huge hassle. I had better luck with my iphone but it wouldn't always sync together. The software is also really buggy. It crashed multiple times while going through the menu. The vio itself is pretty small and compact. Results were all over the place and I couldn't take it seriously when it came time to actually use it. I think at the end of the day, a serious breathalyzer is probably going to cost you more than the vio and this is simply one of those cases of you get what you pay for. There's really not much else to say because it was a huge disappointment.

      If you follow the parameters, seems like a good tool. Of course, most people (including myself) won't have any method of checking accuracy. It does seem relatively accurate judging by my knowing myself & my limits. It seems to drain it's battery very fast, however, so I'd recommend pulling the battery when not in use. Also, it sometimes missed it's own prompts (maybe because of battery life?) In that it says "blow" but is still in its "warm-up" phase. Like I said, it's a good tool & with having a reference. Way cheaper than a dui or dwi.

      I really love how the breathalyzer connects to my phone and not only states your BAC, but also predicts when you will be sober and how you may feel. The only downside to this product is that there is a glitch that happens here and there. It happens when you are told to"take a deep breath" and then the "blow now" screen should pop up, but sometimes it doesn't. My tip would be to delete the running app and try again, other than that, its a really nice tool and a greta price!

      Not very accurate, but fun

      I had a lot of issues with accuracy on it this device. My friend has a professional one and this one didn't come close to it. We also had times of it saying we were sober when we weren't, or even once we had the most drunk guy at the party blow a 0.06. He was definitely not legal to drive. The app is easy to use, as well as the device. It was a very fun item, but with it being so inaccurate, there was no point to have it.

      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.
