What Changed After Using Auru
The #1 Breathalyzer That Actually Works!

Susan H. , 65 Verified Buyer"I'm 65 and I have been having wine with my husband at dinner for forty years. Three weeks in with this thing I have learned that two glasses puts me over the limit more often than not. Three weeks ago I would have driven home. Now I sit at the table another forty minutes. The number on the screen is the only thing I trust. Bought a second one for my daughter."

Sean J. , 63 Verified Buyer"Bought this after my golf buddy got a DUI driving home from the same dinner I was at. Three beers, blew a 0.09, his lawyer cost him $11,000. I keep mine in the glove box. Use it every time before I leave the clubhouse. Most days I am at zero. The days I am not, I read the paper for an hour. Same sensor cops use. For 85 bucks this is the best money I have spent in years."

Linda T. , 59 Verified Buyer"I have three kids in their twenties and two grandkids with new permits. After a girl in our church died last spring (she was 24, her friend had been drinking) I bought five of these. One for me, one for my husband, one for each kid. My oldest son called me three weeks later and told me he had used it twice and taken an Uber both times. That phone call was worth every penny. Real number on the screen, not a yes or no. Easy to use. Buy one for everyone you love."

David O. , 57 Verified Buyer"Bought this skeptical. First time I used it I had two beers and a bourbon over three hours and blew a 0.07. I would have sworn I was fine. I have been using it every Friday and Saturday for two months. The number is almost never what I would have guessed. If you are reading this and wondering whether you need it, you do. I was wrong. So was my buddy who got the DUI. Buy it. Stop guessing."

Why "I feel fine" falls short.
Most drinkers trust how they feel. They count drinks. They wait an hour. They drink water. But by the time you feel impaired, you've already been over the legal limit for 45 minutes. Feeling has nothing to do with your number.
What feeling fine misses
"I Feel Fine" Is The First Thing Drinking Turns Off
Counting Drinks Is Wrong By The Second Drink
Waiting An Hour Per Drink Is Folk Wisdom, Not Science
Coffee And Water Do Not Lower Your BAC

We keep this in the center console and use it whenever we're out with friends. It's quick, easy to use, and gives us real peace of mind instead of guessing. I'd rather spend a few seconds checking than spend months dealing with the consequences of making the wrong decision.

I bought this after seeing a friend get charged with a DUI even though he genuinely believed he was under the limit. The accuracy and build quality impressed me right away. I've recommended it to my coworkers and family because you simply can't judge your BAC by how you feel.

The build quality surprised me. It feels like a professional device, not a cheap gadget. The readings are quick and consistent, and knowing my actual BAC instead of guessing is worth every penny. I honestly wish I had bought one years ago.

Helps protect your family before you turn the key
Two drinks at dinner can put you over the legal limit and leave you feeling completely fine. Body weight, food, sleep, medication, stress, and the time between drinks all change your number, and none of them tell you what it actually is.
What earlier visibility changes
Your BAC can climb without you feeling it. When AuruBlow shows you your real number before you turn the key, you and your spouse have time to wait it out, call a cab, or stay another hour. That decision, made before the keys are in the ignition, is the entire difference.
95%
Drove home with full confidence in their number
75%
Avoided at least one bad decision in the first month

Based on 900 internal studies and customer feedback surveys.
The Science Behind AuruBlow
Measured. Not Assumed.
AuruBlow uses police-grade fuel cell technology to give you your actual BAC reading, not a guess based on how you feel. Your body lies. The number does not.
Real Numbers. Not Yes/No.
Cheap drugstore breathalyzers tell you if alcohol is present. AuruBlow tells you exactly how much. The difference between 0.04 and 0.09 is the difference between driving home and a 14-year prison sentence.
The Decision Happens Before They Keys.
Knowing your number before you put your hand on the ignition is the entire purpose. Once the car is moving, every option costs more. Once the lights are flashing behind you, your options are gone. AuruBlow lives in the 30 seconds where the right decision still costs nothing.
Don't wait for the cop to do it for you.
Drunk driving is the #1 cause of preventable traffic deaths in America. The real risk is believing you're safe because you feel fine, when feeling fine is the very first thing alcohol takes away.
Built with officer insight. Built to save lives.
Police officers respond to DUI calls every single night. The pattern is always the same. A driver who thought he was fine. A drink count that was off by two. A family in the other car who didn't see it coming.
