BACtrack C8 Breathalyzer | Professional-Grade Accuracy | Optional Wireless Smartphone Connectivity | Compatible w/ Apple iPhone, Google & Samsung Android Devices | Apple HealthKit Integration

Works well. Easy

Honestly, I mostly bought this for fun. I rarely have a need to travel after drinking, but I thought it would be a fun little toy to have around. It has been very reliable and accurate, measuring accurately against a police calibrated unit that I often have access to. It's very compact and can easily be carried in my pocket. The biggest payoff has been breaking it out at parties and having friends realize that maybe they aren't as sober as they think. I am sure that it has kept many of them from attempting to drive. No matter what your purpose, if you drink it's definitely worth having around.

I have only had my breathalyzer for almost a week. Here's what I love so far...The Size of this breathalyzer is fantastic. The unit worked first time after put battery (1 AAA) blew until the beeping noise stopped after watching the very clear countdown from 5. I had not been drinking and did blow a 0.0 first time. When asking my son and husband to try, they both blew the same 0.2, but I was informed by them that they both used mouthwash that morning (test was about 3pm) and it does detect the alcohol in the mouthwash. BTW, using mouthwash to hide drinking is always a bad idea, it will elevate your numbers and most police are wise to the smell of fresh mouthwash.This little cutie also has a wonderful addition where it tells you after you blow and get your rate of alcohol, the amount of time you need to stop drinking and wait to drive. Incidentally, when it was only 0.2, it said to wait over an hour to drive without impairment.I also purchased the case that is available for this item and so glad I did. The case will keep the unit safe as well as clean. It is a hard shell with a zipper. I have the extra mouth pieces I purchased also in the case, in the other pouch available. If you keep the case and unit in your purse or car, you will always know the answer to that very important question... "To drive or to Uber?", as well as how long you should wait if you still want to take your car.I believe this is a small price compared to getting pulled over and in trouble. The costs of time off, and other legal issues is far more expensive vs the purchase of this little gem. I will get back and review again after having it for a few months.

This is a great little device. Great for personal knowledge.

Works great but it needs to be sent in to the company for calibration, which isn’t mentioned in description. Sounds like a hassle.

It’s cute, and compact. It will easily fit into a pants pocket. It runs off one AAA battery.It’s made of plastic, but feels solid and well built.You can use it with their app, or standalone. If you are comfortable with basic smart phone operations, you will have no trouble operating this device with the app. Otherwise, the standalone setting is simply to use.The bottom line is that this item is a novelty. It is best used for a drinking game at party, rather than to accurately indicate your BAC when you are considering driving.The accuracy is very inconsistent. I used it twice within about 30 seconds apart, and it came up with two different readings.

Accurate and consistent reading. I would recommend to wait a few minutes after last sip or eating something or drinking water before taking a reading. This will help ensure that you get the most accurate results.

Seems to be extremely accurate, as is the time until sober. Bought a different brand initially for half the price hoping to save money and it didn’t work at all. It’s worth the extra money to buy this one.
