The BACtrack is a convenient breathalyzer and it's consistently delivered reliable readings compared to a borrowed, higher priced breathalyzer I used along side of it. Ready for immediate use (no warm-up time) once I turn it on, it delivers results within 13 seconds. This means you won't be stuck staring at the screen for long. It will save you 10's of thousands of dollars in fines. Not to mention the grief of being owned and directed by a largely unsympathetic government stooge that seems to hope and cheer for your failure of non-compliance. It's one of the many tools that's a must for anyone wanting to exercise your Freedom and Your Individual Rights as a US Citizen. Be the captain of your life.
Pro Tip: The sanitary tips included are dishwater safe.

It works, but take more than 2 measurements and wait at least 20-30 minutes before use
So I liked the idea of a keychain breathalyzer, but its not as convenient or accurate as advertised. I do not drive past 0.06 and this is not at all suitable for someone who wants to pace themselves and would be dangerous for those who drive just under the legal limit.The variance between measurements is easily +/- 0.02. You can read 0.08 15 minutes after one beer and it will fall to 0.00 after 30 minutes.Use of mouthwash takes 30 minutes to go from 0.11 to 0. As you can see, the suggested 15 minute interval in manual is insufficient for a completely accurate reading.I am not sure if my expectations were too high for the product, but it is better than nothing, but there are superior products on the market. In practice, it is functional but you have to not eat/drink for 1 hour, take at least 2 measurements 10-15 minutes apart and the average of this is somewhat reliable. A typical reading series without food or drink waiting 5 minutes may look like; 0.08 ,0.06,0.10, 0.08,0.08,0.06,0.08,0.06 so I would infer this would be 0.075 but the 95% CI would be 0.06-0.092. Its fun having a cheap product that correlates with BAX, but if your intention is to keep yourself out of trouble while driving close to the limit you should probably invest a bit more unless you enjoy doing drunk statistics. If you have this good of a memory on your nights out, you could probably just get the same estimate from writing down your servings and using an online calculator with body weight. Unfortunately people who drink more than one type of beverage will usually not know the alcohol content or remember how many, so this fills that gap, but I would advise spending a few more bucks for the better one.I've also seen false positives. After testing, I accidentally pressed the button without blowing on it and received a rating of 0.02, suggesting the device does not check if you are using it appropriately and assumes you are.Update:Died about a year later so I decided to go with another brand. Its nice for the money, but wouldnt recommend. The accuracy was never good without averaging, but the dealbreaker is really the low product life. I had assumed that semiconductor would be more durable but less accurate, but its really not great on durability aspect either.
