BACtrack C8 Breathalyzer | BAC Alcohol Tester | Optional App

Very accurate, small sample and quick results that match professional/legal devices. worth every single dollar. know before you drive with confidence

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!

This thing is great. I got a breathalyzer in my car, so I wake up and use this mobile breathalyzer, to help me know if I can drive that morning. Only got one month left with the breathalyzer in my car, then it's out, all thanks to this little guy. Yes I drink daily. Yes I'm a alcoholic. Yes this thing is worth the money. It has a count down on when your sober as well, and there's been a few times I'll stay up just to pound water and this thing hasn't let me down yet. Most mornings I can drive even after a few beers the night before, because this little guy tells me when I'll be sober. Def recommend. Long lasting battery in it to, haven't had to change it out yet :)

The BACtrack C8 Breathalyzer is marketed as a professional-grade device with optional wireless smartphone connectivity, boasting a compact and convenient size paired with a sleek, modern design. Its portability is a definite plus, making it easy to carry in a pocket or bag, and the aesthetic is appealing for a breathalyzer, with a polished and user-friendly look. However, the core functionality—accuracy—falls significantly short of expectations. Despite its professional-grade claim, the BACtrack C8 delivered wildly inconsistent readings during testing. Over a span of five minutes, I conducted five tests using consistent breath pressure, yet the results varied dramatically, with differences as high as 0.075% BAC. Several readings incorrectly indicated an over-the-limit BAC, while others failed to provide a reading altogether, which raises serious concerns about reliability. This level of inconsistency undermines the device’s purpose, as precise and dependable measurements are critical for a breathalyzer. While the optional smartphone connectivity is a nice feature in theory, it doesn’t compensate for the core issue of inaccurate readings. For casual use, the BACtrack C8 might seem like a fun novelty item, but for anyone needing reliable, accurate BAC measurements—whether for personal safety or legal purposes—this unit is not up to the task. I would recommend looking into alternative devices with proven accuracy and consistency. Rating: 2/5 – Sleek and portable, but unreliable readings make it unsuitable for serious use.

This is a handy device to carry with you especially when traveling or going to an event with drinks. Each person has an individual mouthpiece instead to straw like attachments on other devices. It is very accurate and if you have a reading on it, it gives you a time of when you will be sober to drive.

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.

Incredible product. Works just as it should and worth its weight in gold.

Great stuff! The video was also very informative and love the ending quote from the guy. “If you’re drinking, call an uber .. (then) call her up!” EDIT: I am editing this review because it has saved my buddies butt while getting pulled over. It is insanely accurate, but please keep in mind to take 2-3 samples with the breathalyzer airing out for a bit between takes. It can be a good averaging. I’d also like to shoutout their WONDERFUL support and warranty. I’ve been through 2 of them so far just due to wear and tear, and maybe I’m a little more rough on mine (my friend has had one of months and no issues) or just bad QC that rears its head early on.. But they are always happy to replace them no question asked.

Love it ! Works great and accurate . Nice and compact

Solo espera 20 minutos después de un alimento, bebida o cigarro para que el aparato de una medición precisa, no lo he usado con el celular ya que no es necesario a no ser que quieras tener un seguimiento de tu actividad alcohólica :3

Compact and useful for my teenager who has just come of drinking age. A great tool to keep him safe and help him make the right decision when driving (ie not to when he's over).

A priori está siendo bastante preciso. Las medidas corresponden con lo esperado en función del alcohol ingerido en cada caso. el aparato es muy pequeño y podría perderse, pero es cómodo de llevar encima. se usa con o sin conectar al móvil, pero hay que cambiar cada vez el modo antes de empezar. es mas sencillo usar directamente que con App y la pantalla da el valor de alcohol en aire espirado, horas hasta 0% y algún mensaje adicional.

excellent produit, très efficace et très précis si on l'utilise en respectant les consignes d'utilisation avec rigueur .... je conseille ce produit
