BreathKey Keychain Breathalyzer

BreathKey keychain breathalyzerThe BreathKey breathalyzer, a product of OmegaPoint Systems of Ohio, bills itself as "the smallest breathalyzer in the world and the only digital keychain breathalyzer approved by the FDA." You can read more at the company website.

According to the site:

BreathKey is one of the most accurate and affordable units on the market today. Developed by the same engineer who designed the breath alcohol ignition interlock systems used by the courts in almost 40 states, BreathKey, with its keychain design, is the smallest, lightest, and most reliable digital breathalyzer on the market today for the price. It combines lightweight portability with accuracy and makes for a reliable breathalyzer you can depend on.

BreathKey gives you an accurate and reliable reading each and every time you use it. The BreathKey pocket breathalyzer measures your blood alcohol level (also known as blood alcohol content or BAC) and gives you quick results so you can plan accordingly.

At the site you can also see a comparison chart, pitting the BreathKey against other popular, low-cost personal breathalyzers. In addition, you can enter your email address to receive a link to a report, "Breathalyzer Buying Guide: 9 Things You Should Know About Personal Breathalyzers.” (For a 2013 report at my new website, see a review of the BreathKey Keychain brethalyzer.)

It is difficult to find objective breathalyzer reviews online. In November 2006 Popular Mechanics reviewed three portable breathalyzers and wrote of the BreathKey G10:

Unfortunately, the BreathKey was inconsistent, with a tendency to give lower scores than the other models. Worst of all, it failed to detect when the subjects reached illegal levels of blood alcohol content.

At the time of writing, had 40 customer reviews of the BreathKey, with more than 80% of the users awarding it four or five stars (out of five).

Here is an excerpt from one:

The "Breathkey" is a very compact, light and convenient device. It seems accurate and gives me a reading in line with how I feel. It reads out in thousandths of a percent - there's a world of difference between 0.081% and 0.079% in terms of a DUI. I like it more the longer I own it. I have just purchased a second BreathKey to keep in my car, whilst the other one lives in my briefcase. I live in the Sonoma Wine Country and go on a lot of tastings. I now find I spit much more wine than I'll swallow.

And another:

The main reason I bought this gadget was to ensure that my BAC was zero the morning after a night of drinking. Although the accuracy is a little sketchy, it gives a good ballpark BAC and I trust it when it says zero, which is all the peace of mind I need. I don't recommend buying this so you can drink then drive, thinking you are under the legal limit. It's not accurate enough for that, not to mention that would just be a stupid plan!
