Emma
I had an older breathalyzer before but it was slow and inaccurate so Alcotest Pro is a huge upgrade. It’s way more accurate and i love how simple it is since you just click one button to get your results in seconds. It’s definitely worth the investment for all responsible drivers.
Carlos
I always keep my Alcotest Pro in the glove box just in case. It’s small, easy to use, also so hygienic without mouthpieces? Love it. This breathalyzer has already stopped me from driving when I thought i was fine but actually wasnt. I feel so much safer knowing i can quickly check myself before getting on the road. Honestly, don’t take any chances and get one!!
Douglas
I was a bit skeptical at first but after using the Alcotest Pro a few times, I’m sold. I’ve compared my readings with the ones from the bar’s machine and they’ve been spot on every time. It’s way more accurate than a couple alcotesters i had before and now I never leave the house without it when I’m going out.

Hygienic solution
I think its biggest win is the no contact sampling because you don’t need to waste money replacing the tubes and as i had to with my last breathalyzer. Plus the response time is immediate and no lagging after months so definitely recommend it for any driver out there!!

Saves me from unwise decisions
Ive been using it for about six months now and i couldnt be more pleased. I love how fast and easy it is to use as you just press a button, wait a few seconds and boom you have your result. I use it after a night out with friends to make sure im under the limit before driving home cuz one time i was sure i was fine but it turned out i wasn’t so now i always rely on it.

Tried and tested reliability
The accuracy of the alcotest pro is what really sold me. I’ve tried a few other breathalyzers before but they were always inconsistent especially with time. I’ve compared the results of this one to the machines they use at bars and its been spot on every time so i have no doubts that i can drive safely if this breathalyzer deems so.

Helps me avoid DUIs
it’s become a key part of my routine whenever I go out drinking since i can rely on it completely. Readings are always accurate and instant. I used it once after a wedding where i thought i was totally fine to drive but it showed I was just barely over the limit, so I waited an extra hour. Avoided a potential DUI thanks to this!

No more stressing
Im a lad who likes to unwind with friends and always been nervous about driving afterwards but with alcotest pro i finally found my peace of mind! Its super fun to use and shows precise results every time, so no more stress for me lol

Compact and long lasting
It’s so compact and portable. I bought it because i do a lot of work events where there’s drinking involved, and I wanted to make sure i could safely drive home afterward. Another thing i find praiseworthy is battery life. One charge lasts me a very long time like several weeks with my frequent uses.

Even a child can operate this
i’m not great with gadgets so I rly was worried it’d be complicated to use, but it’s literally one button and done. You press it once then wait for the beep to blow into the device and in a second the reading is tehre. It’s as easy as it gets.

Never leaving home without it
I bought the Alcotest Pro for my husband and we both use it regularly now. It’s so easy to carry in the car or even in his pocket when were at out. One time after a few drinks at a BBQ we were about to head home, but I asked him to check with the Alcotest. Good thing we did, because he was over the limit. An amazing investment!

Meet Our Expert,
Traffic Safety Expert
One of the biggest issues I deal with is people thinking they’re safe to drive after drinking when they’re actually over the limit. This is where the Alcotest Pro makes a real difference. It provides accurate, reliable BAC readings, ensuring drivers know when it’s not safe to get behind the wheel. I’ve compared its results to professional-grade machines, and it’s always precise. The fact that it’s portable means people can check themselves before driving—something that could prevent serious accidents.

Frequently Asked Questions
How accurate is Alcotest Pro?
It provides 99% professional-grade BAC readings. The device uses the DFFA Duel Filtering Algorithm to deliver accurate results.
Can I use Alcotest Pro to check if I am legally allowed to drive?
Yes, Alcotest Pro tests your deep lung breath to measure alcohol in your system precisely. It’s aligned with FDA and DOT Standards, so you can rely on it.
Do food, mouthwash, or medications affect the Alcotest Pro’s results?
Yes, they may because they may contain bits of alcohol. Though Alcotest Pro rules out false positives, it’s better to be safe. Wait at least 15–20 minutes after using these products before testing.
