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.

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!

Nice little unit although gettign it to display remaining time to drive without going into the app would be good

Very poor quality Bought several as gifts and several defective

As someone with a DUI on the past, accurate readings are very important to me. Every other brand I’ve used has given results all over the place and were incredibly inaccurate. I did my research and the C6 has been shown to produce accurate results in an incredibly small form factor. Just look it up on YouTube and you will see its THE one to get. A close friend happened to show up at my house as I was getting it from my mail box and she was the first to test it after me blowing a .000. She is much smaller girl and thought she was legal. I'll just say she was a LOT higher than she predicted. I immediately bought another C6 for her. everyone who drinks should have one in their glovebox.

This is compact and easy to use. I don’t know why I didn’t buy a breathalyzer sooner. I have always struggled with blackouts from alcohol. I’m sure it has to do with drinking liquor and not eating enough when I drink. This was a huge (and unsafe) struggle all of my college years and into mid 20s. I don’t drink all that often anymore, but when I do, my tolerance is even lower now. Having this breathalyzer really helps me pace myself. You’re supposed to wait 20 minutes after drinking before testing, so I try to be mindful of that 20 minute pause, and then test. I can now gauge how much I’m being impacted by each drink. I’m a numbers person, so being able to see a number and quantify the effects of each drink really helps me self monitor. I’m sure most people use it to make sure they are safe to drive. We will use it for that too. But helping to prevent blackouts was a huge appeal for me. I know not everyone experiences that with alcohol, but if you’re someone that does black out easily, you know how scary that can be. I’m really happy I bought this!

I bought two of these. One for a while elephant at Christmas and one for my husbands stocking to be silly. Both recipients loved them. We had so much fun on Christmas night checking who had the highest BAC.

2026-01-24

I ordered 2. They were easy to use and both agreed for the BAC number. Now we can both be legal whether we are together or apart.

I am so glad I got this. It is so easy to do and in the long run could save you from harming yourself or someone else. Small enough to keep in your purse. My husband and I always use it. I plan to get one for my kids.

Part of my job and sales is to take clients out for lunch or dinner. Social drinking is a thing. This helps me keep in touch with my responsibilities.

This is my sixth trial of a different product from them. The first time I got the C6 about four years ago, maybe three, it worked great not an inaccurate trading at all but ever since that one broke and I bought the five other ones they will be throwing out random numbers Every blow. They offered to calibrate it, but if it didn’t work the first few times every single device (different models too) I feel that there’s no point of calibrating it since they apparently calibrated before they send it out and package it.
