I highly recommend this product for reliability, portability, and ease of use!
I was looking at purchasing a BAC device for a few years. I was hesitant to spend the money, fear it wouldn't be reliable, and if I thought I had too many then there really wouldn't be a need for proof. Well, we had a friend who recently received a DUI when they didn't believe they were over our state's .08 limit. They ended up having to get a device installed in their car that keeps the car from starting unless they were below .02. They supplied them with a portable breathalyzer to make sure they were low enough before attempting to blow into their car device. I started using their breathalyzer to keep an eye on my level, out of curiosity. The strange thing is I kept creeping over the legal limit when it didn't feel like I had much to drink at all! So I decided on making the decision that I needed one of my own. I compared the C8 to the one provided to our friend. The readings were the same measurement to the 100th and over many tests throughout the week. The same, every time! Now, I make sure I don't get that last alcohol drink, drink water and let time pass before I drive. Now I have proof I am over, even though I don't feel like it. It's so true... you can't tell when you reach the legal limit! I am so glad I purchased this before something bad happened to me or anyone else! Also, important note... To get the reliability of any BAC device, you need to wait at a minimum of 15-20 minutes BEFORE you test or the alcohol on your breath will throw it up and out of range. Thanks, BACtrack! I highly recommend this product for reliability, portability, and ease of use! I keep this with me at all times and if I forget it at home, I don't drink. I learned that I can't trust a feeling over being over the legal limit and need absolute truth!

Reassurance For Peace of Mind
Very very very accurate. We've really put it thru several times tests and with heavy scrutiny. It performs precisely as it should. This is total peace of mind and very sobering!

Excellent unit, though not as good a value as the C6
I actually bought this to have a second unit since I liked my C6 so much. The only real difference is that this one has a bigger screen, and shows you your estimated time to sober on the unit itself without having to pull up the companion cell phone app (which I also LOVE, and which works with both units). For the price and size difference, I'm not sure that I really care. And the C8 is a little less quick to use for it - you have to manually turn it off after the test, or it'll be ~40 seconds of telling you stuff on the screen before it shuts off on its own. Not a huge deal, but again, for how much cheaper the C6 is, I kind of prefer that option. But all in all, if you do want that estimate, the C8 is a great option. I rated the accuracy only 4 stars because my unit seems to read a fair bit high compared to the C6 on the exact same breath, and given the circumstances I tend to trust the C6 more. I'm not sure if that's the unit itself, or my C6 being in need of calibration. On the plus side, measuring high is the better kind of inaccuracy to have in this case, so that's good.

Not working
Bactrack asked me to write a review, but they might not like my review. Tl;DR The device is not working, always returning 0. I have tried it 4 times, the time where I drunk the most was with 1 glass of wine and 2 cocktails, with a light meal, and still saying that I am sober (I was definitely tipsy). PS: I reached out to the support and made sure I was using the device properly, waited the appropriate time before using the device. Longer version: The support told me that you are supposed to wait up to 45 minutes as it can takes that long for alcohol to reach your bloodstream. And you should wait at least 15 minutes after your last sip. Obviously height, weight, gender, metabolism, food consumed, how quickly you drink will affect the results, but on my side, it has always returned that I was completely sober. The device is small and light, so easy to carry. It's quite quick to turn on, easy to us. I love UX of the device overall. The only minor comment is that it is hard to open the battery section. I am using an iPhone app, it's not a high-quality UX but does the job. My main comments are that it's sometimes slow, especially when you want to go through the different screens of a recording. I have to wait a few seconds of it to load/unfreeze. It also offers the ability to record what you consumed, but it's very not user friendly, and it requires a lot of effort to log a drink when in my opinion it should be super fast and easy. All this slowness/bad UX is fine as I am at home and have plenty of time to dedicate to that, but in a non-shelter in place situation when someone would like to use these features, I think it would be a bit more frustrating. But again to be fair, the MAIN feature of the device which is to inform you about the alcohol in your blood is fast and easy. It also does not offer a much data visualization, for instance I would love to be able to watch my drinking trends. I am using this device mostly to understand my alcohol consumption and see if it's reasonable. It might not be the goal of the main customer target, but I would really appreciate that feature. The customer support said that they would initiate shipping to inspect the unit, I am not super excited about having to do this but no choice... I will update my comment once I receive a new unit.

A fun product.
Before I start, I should say to never drink and drive. Buzzed driving is drunk driving. I've always wanted a breathalyzer for fun. I finally pulled the trigger and bought this one. All I can say is it's fun to play with! The product is insanely easy to use. You turn it on, it warms up, and you blow when it says to. The app took a bit to get connected, but it does connect (but it's not required for use). Connecting it gives you some added features, such as a chart for over time, and the ability to compare your BAC to others. One of the nicer features about the C8 is that it tells you an estimate on how long it'll be till you're back to 0.00% BAC. Accuracy-wise, it'll never be up to par with a professional one, but it's accurate enough for home use. When I tested it I was getting a error range of +-0.004%. The one downside to it was the plastic that the screen is made out of. I dropped it within the first 10 minutes of playing with it and got a nice scratch across the screen. Overall, I would recommend it. Just don't expect police equipment accuracy from it.

Meh
Fuel cell sensors, unlike this one, are accurate for 12 months. They cost more, btw. The cheaper models, like this one, are accurate for 3-6 months. You can have them recalibrated but not sure what that costs. Of course, after recalibration, the accuracy is shorter lived. Excessive use shortens life. I'm very OCD about how much I drink when I do. It's actually easier to measure your drinks and use an online free calculator. Just my opinion.

I love it and my friends love it now too :)
The BACtrack C8 Breathalyzer is a great device to keep in your car. I like having it because it gives me a way to check my alcohol level before making the decision to drive. If I've had a few drinks, I can test myself and make a more informed decision rather than taking unnecessary risks. Before I had a breathalyzer, I would sometimes take chances and always worry about getting pulled over. Now, I have peace of mind knowing I can check my alcohol level before getting behind the wheel. I highly recommend this device to anyone who wants to be more responsible about drinking and driving. One important safety note, a breathalyzer reading below 0.08 percent doesn't necessarily mean you're safe or legally permitted to drive. Alcohol can continue to affect your judgment and reaction time, and readings can be inaccurate. The safest choice after drinking is not to drive, even if the device shows a reading below the legal limit.

Easy to use & fast
Super easy to use, and ads a reality element to going out. Gives you the knowledge of how you're doing without chancing it. It's nice to sync with the phone, but I find I use it more in stand alone mode, which is quicker.

Werkt goed en snel
Niet eerst veel (verse) lucht inademen. Dat geeft de beste meting. Het apparaat heeft niet veel adem nodig, maar wel gelijkmatig vooor +/- 4 sec.

Best thing I've bought in a while
I bought this breathalyzer so that I could feel confident the next day when driving after a night of drink. It has also become useful as my teenage daughter has gotten to that age and puts my mind at ease when needed. I've used it both with the app and they stand alone use. Very handy to be able to have both. I would highly recommend it. I feel confident in its results. Point to note.. no food or drink for half an hour before testing to get the most accurate results.
