“Bought this a couple months ago. The only reading I ever get is "FL", over and over. I was actually very excited about using with my friends. Disappointed about it being a dud :(”
“My phone recently upgraded from Android 6 to Android 7. It broke the communication with the 2 Bactrack Mobile Pro units I have. Needless to say, after buying 2 Mobile Pro units, I was not happy. I had some back and forth with customer service and finally Joshua at Bactrack very kindly sent me one of these units I installed the Mobile app on my tablet and so was able to test this version against 2 of the more expensive Pro units. The Pro units have a sensor with better technology. After multiple tests the readings on this unit were very comparable to the readings of the Pro units. IMHO this unit is reliable and can be trusted if used as instructed. It is also, althoug not as accurate, much smaller, faster, and easier to use than the Mobile Pro version. A great return on your dollars!”
“I bought three of these over a year ago and gave them as gifts. I kept one for myself and I have used it regularly and it works perfectly. An amazing product at a very affordable price.”
“I ordered the BACtrack Keychain because I was required by the court (DUI) to have an interlock device in stalled in my car for one year (one of those breathalyzer/starter gadgets). I'd heard it was a good idea to do a "pre-blow" into a 3rd party BAC device, to make sure something you ate or drank doesn't result in a false positive. This is critical, because the info of every "blow" is sent to a data base via a cell-phone type cadet also installed. So, failure to be able to start due to a positive BAC is bad, resulting in extended probation periods, more fines, or an increase in sentence (i.e. more jail time, etc...).
After reading a few reviews (here, in fact) about the Keychain not being so accurate and also short lived before the need for recalibration (also short battery life), I immediately order the BACtrack S80 Pro (long battery life, only yearly calibrations). I've found the S80 to be VERY accurate. The BACtrack Keychain consistently reads inaccurately high BAC. Granted its super cheap and uses a different technology than the S80 and/or police issued breathylizers.
So, in conclusion... the BACtrack Keychain is a really cool idea. Great form factor, and ridiculously inexpensive. However, if your "freedom" depends on an accurate BAC pre-blow, go with the BACtrack S80 Pro. I keep the Keychain version in the same nice S80 case it came with, but rarely use it. Sometimes I do, but only to confirm its always a higher reading than the S80.
All that said, someone who does not have any legal issues, who just wanted convenient way to find their BAC before leaving a party or a restaurant to drive, the Keychain might be a perfect fit.
Cheers ya'll!”
“Who really knows what their BAC is? I know I didn't. It may sound silly but with the BACtrack I am learning how alcohol impacts me. It is scary how I can easily get to .08 and feel like I am perfectly fine. Even worse how much alcohol is still in my system the morning after. I'd recommend this as a must have for everyone young and old alike. It would be handy to solve the "I'm OK to drive" arguments that often occur after a night out. Be sure to wait about 20 minutes from your last drink in order to get the most accurate reading.”
“I've had this for a while now and even after not drinking for twelve to twenty four hours, it will give me a reading of .10
Sometimes after it gives me that reading, I'll blow into it again and it will give me a .0 or a .05
Seems to be all over the place.
Feels like money down the drain.”
