Perfect for any social situation, from happy hour to dinner parties, the tiny BACtrack C8 personal breathalyzer will raise your drinking IQ, helping you and your friends drink smarter. BACtrack has created one of the best breathalyzer apps on the market. Pair your bluetooth breathalyzer or bluetooth-enabled keychain breathalyzer to the free app and you will achieve much better results than using a simple bac calculator. This home breathalyzer test (or alcohol breath analyzer) is also sometimes known as a blood alcohol tester or an at home breathalyzer. Whatever you call it, you know you're getting the most accurate results in the industry. Review: No issues - Nice quality! Review: Very accurate and easy to use. - Really good. App is easy to use and seems pretty accurate. We’ve tested it with several people and kept track of what each of us have drank and it matches the amount of units very closely. Obviously I wouldn’t recommend using anything if the law depends on you being sober but this is very good for everything else. ## Features - ESTIMATE YOUR ALCOHOL LEVEL WITH PRO-GRADE ACCURACY - Powered by BACtrack's patented BluFire Fuel Cell Sensor, the C8 utilizes the same professional-grade technology trusted by hospitals, clinics, and even law enforcement. - KNOW WHEN YOUR BAC WILL RETURN TO 0.00% - BACtrack's innovative ZeroLine technology estimates the time until your BAC is 0.00%, allowing you to quickly and easily know where you stand. - CALL AN UBER - Remember, the only safe time to drive is when your BACtrack shows 0.00%.
