Know this instrument shouldn’t be used to determine whether you can legally drive & may not be 100% accurate, but it does take the guess work / doubt out of the equation. I Drive for a living & feel with complete confidence that this was the best purchase for me in a long time ! I have brought it with me everywhere I go since the day of the purchase. It’s small / compact size is very easy to keep on yourself, I let other friends use it to prove they shouldn’t be driving under any influence. By all means it doesn’t cure the DWI problem , but I’m positive the instrument has already saved lives. Thank you for such a great product. Rich C

If you want a reliable, compact breathalyzer, the BACtrack C6 is a great choice. It gives you both standalone use and app‑connectivity, and its fuel‑cell sensor makes its readings relatively trustworthy—especially for personal, casual safety checks. I’ve recommended it to friends and family who want peace of mind after a night out or who want to avoid “am I safe to drive?” guesswork.

I have been using the BACtrack S80 for years. I have had one in the car, my truck, my Harley and my wife's car for years. Use one each time before driving to avoid driving over intoxicated. It's way cheaper than the alternative of driving under the influence and getting cited or killing someone. I recently bought th C6 and have loved the smaller size as well as the quicker reading time than the S80. I ended up buying 2 more to have in our main vehicles. It so much smaller and can fit in my pocket like a key fob. That means I can take it into the bar in my pocket or my wife's small purse without having to go out to the car to test my BAC. I would highly recommend the C6 and still need one more to put in my Harley.

It works perfectly, I put them on my keys.

My package was left in the middle of the sidewalk, stolen and now the company is refusing to refund me. Do not buy from them.

So far so good! It seems decently accurate but it’s a fun little thing to carry around

Have been testing this out to show my young adults the effect of one or more drinks. Gotta try everything I can to keep them safe!

Ive had a drinking problem for years. This handy Keychain has saved me from several DUIs over the years ! I tell all my friends, if your drinking this is hands down the best investment you van ever make ! Incredible accuracy, the Bluetooth option for your phone has pinpoint accuracy telling you when you will be sober, and checks you to make sure you are not over the limit. Thank you guys again, and again. The term LIFESTYLE comes to mind if your a drinker like me. Incredible product!!

I love this! It keeps me from having that last drink or makes me wait longer than I normally would. If you have issues with it try changing out the battery, any issues I’ve had were fixed by that. I did contact customer service once before figuring it out and they were very helpful.

Have these to my kids in their stockings this past Christmas. The point was to make sure they used them when they went out with friends before getting into a car after drinking. Easy to carry. And friends can use them, too, if needed in a pinch (just wash after). Better safe than sorry!

Enjoy the peace of mind knowing I'm able to drink and ensure I'm not impared when driving. I like the small device and key chain attachment. Easy to use.

I often have a drink or two when out and fear the dwi. I have used this multiple times now and it will show .05 when I’m leaving giving me a piece of mind. I’m not sure of the accuracy since I have nothing to compare it to but, I’ve done the drinks per hour rules and it seems reasonable. I have the keychain version and love its portability and it’s a great conversation piece along with a little reassurance. I would recommend this to anyone that has a few drinks with friends and wants to make sure they aren’t going to endanger others. Remember judgement is impaired after drinking and overconfidence becomes a flaw.

Works much better than others I’ve tried before.

2026-02-11

Very easy to use. Helps to make good decisions on when to drive.

2026-02-11

Works as it says. Perfect pocket sized piece of mind.

I am loving this small little breathalyzer. It accurate and easy to read.

Unfortunately the product did not work as expected. I replaced the battery to brand new one but it worked sporadically (worked one time then 10x in a row I got an error message it was not registering a blow), and other times 'based on what I felt it should be for a reading' didn't provide an accurate reading. Another time 'zero' drinks starting in and it said I was already @ .19. Disappointed as I thought this would be a great opportunity to 'check in on my self' when out having drinks before driving home; and/or share with a friend if I think they shouldn't be driving after too many!
