“I have tested the device against reference standards and have found the measurement uncertainty to be small < 0.002. Bias is significant, but when present tends to slightly overestimate. After sending it in for recalibration, bias was diminished. The natural variability is small SD=< 0.001 at the 0.08 g210l level.”
“I love it, but the mapping function doesn't work any longer and i wish the BACTrack mobile had an LED display on it's side so you don't have to have your phone to get a BAC reading. Also, it would be nice if there was a visual indicator on the device or the app that tells you when recalibrating is necessary.”
“I purchased both the Mobile Pro and C6 Keychain models, and both read consistently. Readings jive roughly with expectations from calculators based on consumption, weight, time, etc, and food ingested (which affects absorption). The Mobile works well through the phone App (iphone in my case). It's small and easy to use, and i like it, although right now I'm partial to the C6 due to its smaller size and standalone capability (no App needed). The calculation on "time to be sober" (i.e, 0% blood alcohol) is consistent with the human alcohol metabolizing rate (0.016%/hr), and with a bit of arithmetic, you can scale to the shorter time to get down to a non-zero level you may feel is safe for what you want to do. I think their quoted calibration cost is reasonable. I'm happy with it so far, and I hope that it proves durable.”
“This easy to use product is a Godsend. My son has an alcohol problem and the BACtrack phone application has kept him accountable to his wife and to me. Thanks so much BACtrack!!”
“Have used it for over a year as backup proof of sobriety for my supervised probationary period and to backup false alarms on my ignition interlock. I use everyday from the moment I get up till I go to bed at random intervals throughout the day to re-establish family trust and to document my sobriety seamlessly with the builtin health app on my iphone. Works without fail every time. Highly recommend the investment. I ordered i online from amazon”
“First and foremost I wanted to have some knowledge into how much a beer is actually impacting my 'legal' drunk level. I've been able to get a MUCH better knowledge of how intoxicated I am now that I've measured my BAC so many times at this point. I'm pretty accurate in guessing even before I take the measurement.
Additionally, I've opened the eyes of several of my friends in similar ways. This device saves lives, money, and everyone who drinks or has friends who drink should have one.”
“This device was great for a few months then rapidly began to show decreased levels. Eventually, it showed 0.00 after a few months no matter my true BAC. I wasn't about to pay for calibration after such a short period of Rome (maybe 6mo). This is a good product for short term use, but expect to pay for recalibration or replacement in short order. I hope their Pro line works better, especially if it is marketed to true Professionals.”
