Fantastic and a must have for responsible drinkers

This is fun to use at home to see exactly how well my body processes alcohol. I love putting those double shots of whiskey back, and I always seem to hold my drink above the rest of them in parties as well. However, now that I can actually see where I’m at in the ‘real’ world... I should probably start admitting that I’m more inebriated than what I truthfully feel that I am. I was stupid to trust my feelings in the past (now all those drives I took, etc... I am filled with regrets even though nothing happened). Also this is a MUST HAVE FOR PARTYING AND BUSINESS TRIPS. This is hilarious to use with friends and coworkers and after all the laughs your group tends to make better decisions without needing to be stick in the mud in the night. Using the BACTrack breathalyzer must have saved lives by now.

I’m a huge heavyweight when it comes to handling many, MANY drinks, but this breathalyzer doesn’t lie, I’m more human than everyone else or even I think I am. Drink responsibly folks. Cheers! 🥃


Reliable, Handy and Affordable!

It is a handy device to have. I do not drive if I've had more than one or two drinks anyhow, but I've been playing with it at the house. Seems to be pretty accurate. I had one many years ago that I always gave very erroneous readings. My father, a Police Officer, told me to trash it. It was all over the place when we compared itto his "real" breathalyzer. This one seems to be very consistent and it seamlessly Bluetooth's to my iPhone and is super easy to set up. Bought it at Costco for a reasonable price. I highly recommend this one!


Why no Apple Watch

I haven’t used this in a year since I was not drinking in the setting where I needed to check my alcohol content before driving and noticed that the Apple Watch app has disappeared ! That was my favorite feature especially now with a new Apple Watch that works better than any of the other ones.. I really hope that this is reviewed and they create the app again I never had an issue with it myself it worked every time !
I’d change my review.
