Don't really care about the mouthpieces because I just use this for personal use, but the device itself is great. I keep in on me at all times as a reminder to stay sober.
Odd that you asked me to write a review on your add-on mouthpieces, but not the device itself. Well since you provided the forum, I'm going to tell you what I think about the BACTrack device. Purposely drinking, even to the point of catching a pretty good buzz, your device showed 0.007. Yes, that's two zeros before the 7. I was trying to show my kids what a great device this would be to learn how unaware they are about their own journey into drinking. I downed nearly a pitcher of alcoholic slushies over half an hour. In other words I felt the affects of the alcohol and your device told me I wans't even 1/8th of the way to impaired.
For many years I had no idea of what my BAC was while out for the night. This device is an eye opener and a life saver for everyone! "Being informed is the first step to making the right choice" and this gets you there quickly!
Thank you for the BACtrack! I purchased this to understand better what it might feel like to be "drunk" though I am not that very often. I truly did not know what it felt like to be at a "0.08" or legally drunk level. I still dont because I have not ever gotten that high of a reading but now I know what level I am at after my one glass of wine with dinner. It is very easy to use and the integration of the phone app is key to its convenience. Thank you!
