With more and more people becoming aware of the potentially life saving benefits of carrying your own personal breathalyzer, manufacturers have moved to make these devices not only more affordable but more compact and portable. Because of this movement, there are now a number of different versions of the breathalyzer keychain on the market, and this segment of the breathalyzer industry is considered one of the fastest growing.

If you are considering purchasing a keychain breathalyzer it is important that you do some homework. As you do your research into these devices it will quickly become apparent to you that there is a wide range in price between different versions of this kind of breathalyzer. You might find some breathalyzer keychains for sale with a price of less than $10, while others range up to around $75. The difference in quality and effectiveness between these units is as wide or perhaps even wider than the difference in price.

Given this wide price range, it is important that you take some time and decide exactly what your purpose will be for this safety gadget. Do you want to amuse your friends at a party, or even try to educate family members at the next family function? If that is your main goal, you can probably get by with one of the cheaper versions. However, if you plan on carrying your breathalyzer keychain with you and using it to decide if you are going to get behind the wheel after having a few drinks, you have to understand that you will not get the kind of results that you can rely on if you are using a breathalyzer that costs in the low end of the price range. On the other hand, most people would say that $69.99 is not too much to pay for safety, and that is the price of the BreathKey Breathalyzer. Of the current Breathalyzer keychains on the market, the BreathKey is the only one that can or should be used for actual decision making regarding drinking and driving a motor vehicle.

The way in which a breathalyzer operates is the key to its accuracy. One look at most keychain breathalyzers will tell you that these are not made with the quality you would want in a breathalyzer that is intended for real decision making. Most have a display that uses color coded lights to tell you what range your BAC (blood alcohol content) is falling in, while a quality breathalyzer keychain like the BreathKey will show you an actual numeric readout of your BAC.

In short, there are several versions of the breathalyzer keychain that are fun for use at parties and family functions. But there is currently only one that uses the same technology as police breathalyzers, and gives you an LED display showing your BAC in numeric form, and that is the BreathKey Breathalyzer. It pays to know the difference before you make your purchase.
