I used to have anxious thoughts and doubts about whether there was any alcohol left in my system after having a few drinks the night before. This thing really keeps everything in check, it’s impressively accurate and gives me real peace of mind.

Works great! I was real drunk. Can’t say if I will buy another one.

If you need or want to know BAC, get it. It does it. And it's easy to teach anyone how to do it.

Most accurate one ive used. Stay safe out there everyone and get this.

This is a must-have anytime you have a drink away from home. The peace of mind is worth every cent. Now I know when it's safe to drive and when it's time to call for a ride home. I love it so much, I've bought ones for all of my adult children as well as my parents. If you're reading this now, it means you've too have wondered whether you or someone you love was safe to get behind the wheel. This is one purchase you won't regret!

Rugged, accurate, quick shipping. However, need to blow very hard and long. Not suitable for seniors.

I have used this quite a bit since my purchase I really like the quality, size and accuracy. Highly recommend this product to everyone. Looking to purchase another for the recalibration times, and for friends and family

I absolutely love this device simply becuase it gives you such peace of mind. What more could you want. I highly recommend it to anyone who wants the same. Rest assured you will not be dissapponted. I only wish I discovered it sooner.

Saved me from a lot of hassle with the State. Just blow in this device and the State doesn't know.

Durable, affordable, solid. That’s the S80. Practically bulletproof, holds low and high temps, shocks, and has 4-digit BAC precision. Simply the best.

Device works well. Took me a few tries to learn how long you had to blow bit the instructions did state 5 seconds. Seems to be very accurate and a nice little machine.

I have had several BACtracks over the years and decided I wanted a professional grade one one. This one fits the bill. Quick and easy to use. It's a great way to get a sense of intoxication. Extremely handy and would highly recommend.

If you're into gadgets, data, and drinking socially like me, this is a fun and responsible tool to add to your arsenal. Easy to use, and seems accurate, as long as you wait the recommended time after drinking to test.

As a former law enforcement officer, this is the best and most accurate portable breathalyzer on the market. I own two of them and they never fail.

2026-01-05

The BACtrack breathalyzer has been an outstanding addition to our routine at Roaring Brook Recovery. It is incredibly easy to use and provides fast, accurate results that we can rely on. It does a great job balancing professional-grade performance with total simplicity. Highly recommended!

I had a 12 year old keychain BACtrack that is still working great. However, I saw the S80 was rated as the most accurate and appropriate for DOT use. I have been very happy with my purchase and enjoy knowing I have a perfectly accurate reading.

Very accurate great for when ur out with friends at a party to check ur levels before getting behind the wheel of a car!! Sometimes you think you’re fine and you aren’t

I originally bought the key chain model and the results were a bit random at times, but then bought this one and the readings are spot on and make sense every time for what we drank. Definitely love this model more! Very helpful to keep loved ones on track and actually prove to someone that they are or aren't ok to drive. I have a friend who is so paranoid he won't drive at all because he doesn't know when it has left his system and this comes in handy to prove whether the alcohol is gone in the morning or not.
