I bought this for a friend who uses it on a regular basis -- unfortunate for her. The ease of use and accurate results make this a great buy.

Everybody should have one of these! Even if you don’t think you need it, it’s great to have for so many reasons. I have one to my teenage daughter to keep in her car, and I keep the other one in my kitchen drawer for my wife and I. It seems much more accurate than the cheapies I’ve tried before, but be sure to wait at least 20 minutes or so after your last drink for an accurate reading.

The BACtrack C6 Keychain Breathalyzer is the best investment I made in a long time.. Cops be on BS so if I know I have been drinking I can test myself before I get behind the wheel of a car to show proof before the cops even try to pull theirs out. Everyone should have one of these. When you go out to dinner or drinks with friends you can al test to make sure everyone is safe to drive

I like it, it works perfectly without any additional tools. there is a beep sounds that tells you when to stop blowing, that is cool, specially when you are drank. My only worry is the accuracy, I don’t have alternative ones to test that, hopefully someone does it in the future.

Bought this as an entertainment piece. My friends and I have used this after having a few drinks. Easy and straightforward to use. Comes with 3 plastic guards for multiple users. You'll probably have to buy more if intending to use it as I do. Can't really speak to the accuracy of readings as I don't have anything to compare it to.

Nice little gadget to have around. I appreciate the option to display results on the unit or track results through the app. It is small and the company stands behind their product. I don't know that I'd pass it around at a gathering like the ads suggest but it is handy to have to know your actual BAC.

Time to Call UBER/LYFT!

This is a great little tool to help the user know when it's time to call for a ride home. My brother is a professional truck driver AND an UBER/LYFT driver on weekends so knowing his BAC is critical to BOTH professions. He likes going out on Friday night for a few, then driving for UBER/LYFT on Saturday/Sunday (no drinking). He "guessed what he thought his BAC was (.04) and this tool readout agreed with his assessment. I feel better knowing that he can use this tool and can call Friday nights if he's close to the limit instead of simply "guessing" & losing BOTH of his driving livlihoods!
