BACtrack Keychain Breathalyzer

The BACtrack Keychain Breathalyzer is an extremely affordable and safe alternative to some of the more professional breathalyzers on the market.  Professional breathalyzers can reach into the $100’s and often use a fuel cell technology that is a lot more accurate.  The BACtrack Keychain Breathalyzer uses a semiconductor sensor to determine your BAC, which aren’t as accurate or consistent as fuel-cell technologies.  However, for the price and the convenience that this little device brings, the readings are much very so in the ball park and can give a very good idea of drunk you really are.

Where To Buy?

We highly recommend buying from (check current discounted price) because you can save about 10 bucks and it also qualifies for free shipping!

The Size Is Perfect

The size of the BACtrack Keychain Breathalyzer is probably have the size of your smartphone and maybe just a little bit larger than the remote (fob) to unlock and lock your car.

Might Be Good For Entertainment Or Gift

Some people use and buy breathalyzers for entertainment purposes at parties.  This isn’t a reason to see how drunk you can get and beat the high score on the breathalyzer, but people certainly get a kick out of using it.  You wouldn’t want to use a professional breathalyzer for these purposes.

What Customers Are Saying About the BACtrack Keychain Breathalyzer

I noticed this small breathalyzer on and noticed how it quickly became a popular purchase.  It currently has 10 reviews with an average rating of 4.4/5 stars, which is really good for a non-professional grade breathalyzer!  By the time you read this, I’m sure there will be many more reviews.

Most of the reviewers are commenting about how surprised they were with its accuracy and consistency for the little money that they paid for it.  Most people have bought it for the convenience and affordable factor that the BACtrack Keychain Breathalyzer provides.

As with all semi-conductor breathalyzers, users do notice and knowledge that some things can throw the breathalyzer off.  For instance, those who have diabetes or on a low calorie diet can potentially have inaccurate readings.  You also shouldn’t have any mints or alcohol at least 20 minutes before using this breathalyzer.

We would recommend buying it if you’re in need of a cheap non-professional option that works well.
