BACtrack Keychain Breathalyzer Review

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.

BACtrack S75 Pro Breathalyzer Review

BACtrack S75 Pro BreathalyzerThe BACtrack S75 Pro Breathalyzer is another solid option from BACtrack line of professional grade breathalyzers.  This breathalyzer uses a fuel cell technology that it enables it to be extremely accurate and comparable to some of the units that the police use.  This technology also allows it to be used in medical testing as well.  Most of the cheaper breathalyzers on the market use a semiconductor technology that’s prone to inaccuracies.  The semiconductor breathalyzers won’t give you a consistent reading back to back like a fuel cell technology breathalyzer will.  They also tend to give inaccurate readings to people with diabetes or those on a lower calorie diet.

Compared To The Select S80

BACtrack also has the Select S80 Professional model which is a little bit more expensive than the S75.  However, to be fair, I honestly can’t find much of a difference other than design.  So, you might as well save some money and pick this one up.

Front Facing Mouthpiece Is Awesome

What I like about the BACtrack S75 Pro is its sleek design and front facing mouth piece as compared to other breathalyzers with the mouthpiece on the side.  It allows you to watch the display as it counts down so you can blow into it.  This eliminates having to twist or turn the breathalyzer when it hits zero.   You have to be able to blow quickly enough for a more accurate reading and twisting the breathalyzer will just delay you.

Features of the BACtrack S75 Pro Breathalyzer

  • BACtrack’s Xtend Fuel Cell Technology
  • Displays 3 decimal places
  • Automatic breath pump inside
  • Takes a deep lung air sample
  • Dimensions: 2.3″ x 4.8″ x 1.0″
  • Weighs about 4.4 ounces
  • Full 1 year warranty

Here’s what’s in the box

  • BACtrack S75 Pro Breathalyzer
  • Carrying pouch
  • Hand strap to tie to the breathalyzer
  • 6 mouthpieces for sanitary use
  • Comes with 2 AA batteries
  • Manual on how to use it

Here’s what customers are saying about the BACtrack S75 Pro

As of right now, there’s 32 reviews on and it has an average rating of 4/5 stars, which is pretty good!  People like that it’s a professional breathalyzer that they can really trust.  One user has a friend that’s a police officer and ran a test between his unit and her S75 Pro and the results we’re nearly identical.

Another reviewer bought this model because DUI’s were on the rise in his city. A lot of people were getting arrested after just having a beer or two.  So, he wanted to make sure that he bought a fairly accurate one that wasn’t going to cost him too much.  He feels reassured that he can take a few tests within a few minutes of each other where each test shows a similar result.

Some people have issues with the rate they have to blow.  You may experience a “flow” error rather easily while others don’t.  It seems like you have to find the sweet spot sometimes.

We like the BACtrack S75 Pro Breathalyzer and feel comfortable recommending it.
