S80 Breathalyzer | Professional-Grade | FDA 510(k) Cleared | 2pk | DOT & NHTSA Compliant | Portable Breath Alcohol Tester | Police-Grade Accuracy | Home & Personal Use | 12 Mouthpieces

I need to have a means to check my BAC before driving. I am a very good driver - in almost 30 years, I have never so much as dented a car I was driving except the one time I was stopped at a traffic light and got rear-ended. That said, just because I think - even *know* - that "I can drive", the law may say otherwise. With limits reduced to a meager 0.08%, I am entirely positive I have driven over that limit before and I don't want that to happen again. I cannot afford a DUI. I shopped around and immediately discarded all of the cheap-o keychain options. I am not interested in fail/pass (read: alcohol present vs. not, at all) device. I want an accurate measurement. If I am at 0.08%, or above, I look to either find another mode of transportation or wait it out some, depending. In purchasing this device, I spent more than I had anticipated, but this is an occasion where quality cannot be sacrificed. It arrived quickly after ordering. Within the box was a nice carrying case, the device, an instruction booklet, a registration reminder, a pair of AA batteries, and a half-dozen individually sealed mouthpieces. I reviewed the instruction booklet. It is front-loaded with a few pages of general information RE: alcohol consumption. After that, there are a couple pages dedicated to the operation of the device. The instructions were stone-cold simple except for ONE thing. It made reference to pressing the "Power Button" which is, in fact, the "Start" button. I took a measurement and it seemed to operate just fine, registering a solid 0.00% result, which is good since it is still the middle of the afternoon and I am not an alcoholic. The device is solidly built and everything fits nicely in the case, which zippers shut. It can easily fit in one of the several storage cubbies in our car. I intend to throw a spare set of batteries in there and leave it in the vehicle. Anyway, my wife and I have an active social life and, quite often, it involves some booze. I'll probably be using this device once a week. I will update this review with tales of "actual usage" as they unfold. I may just "calibrate" it tonight, for kicks. There is nothing I see, so far, though that renders this anything less than a five star product. Only tips are: Have spare batteries. Register the product online (takes 30 seconds). Wait 20 minutes after your last drink before expecting an accurate measurement. Be prepared to send it off for calibration once a year. That should do it. Good luck and stay safe and out of trouble! EDIT: The night I purchased the device, I drank some beers and measured the results. They were exactly what I expected them to be. Measuring after waiting 20 minutes after each beer yielded increasing results. I did this for eight beers. About two hours after no longer drinking, the results started to go downward. I am confident I will not only have a good measurement when it comes time to drive, but I will also develop a better sense of what different levels of buzzed/drunk translate to in terms of raw BAC numbers...and how long those numbers take to diminish after stopping drinking for the evening. This is good information to have. EDIT2: After using this device for some months, I absolutely love it. I have basically trained myself to enjoy the evening, but end it under the legal limit. When I go to the car, I check my level and, almost without fail, I am able to predict what it is within 0.005...just based upon what I have consumed and how I feel. No more guesswork. No more risk. I cannot recommend this enough. I have had friends witness my use of the device (and the eerie accuracy of my predictions..."I feel like about a 0.065"...BOOM!) and they have been quite impressed. Hopefully the behavior will rub off on a few of them and they, too, will render themselves immune to unnecessary trouble. EDIT3: 6/26/2015. Well, some nasty person broke into my Jeep Wrangler while I was attending a rock concert with my son, destroyed my locked glove compartment (but couldn't get it open), cracked open the locked middle console, and stole my BACtrack S80 (among other things). I just ordered $800 worth of Tuffy gear (secure glove compartment, middle console, and rear compartment), so that's not going to happen again, but, more pertinent to this product, I am purchasing the same exact BACtrack S80, again. That is how good it is. Meh. It was up for calibration, anyway.

I bought this for our company holiday party. It's an open-bar affair, maybe eighty to ninety boisterous, twenty-something millennials in attendance; my idea was to hand out wrist bands (Advantus Crowd Management Tyvek Wristbands: they worked great) in exchange for keys/Uber receipts, and make people blow in the breathalyzer to get their keys back. Those who failed the BACtrack could get their keys from the lobby the next morning. Great idea, right? In execution, not so much. Almost immediately my people landed on the idea of having a personal mouthpiece (I bought two fifty-packs of BACtrack Breathalyzer Mouthpieces for fairly cheap, also a smart move) and "competing" to see who could get the highest BAC. Many times I heard, "I'm only at a 0.06, time for another pickle-back/Jamo" followed by, much to my chagrin, a hearty round of cheers. Needless to say the BACtrac S80 Pro Breathalyzer was immediately retired. My wife and I did gauge ourselves at home, for fun, and found the breathalyzer to be rather accurate. Also interesting as that my wife, who weighs less than half of what I do, blows a 0.11 after three glasses of wine where I'm at a 0.05. I will always be DD, with this thing as a good backup gauge. Also important, and this is reiterated repeatedly in the instructions: you have to abstain from consuming alcohol for 15-20 minutes to get an accurate reading, otherwise residual booze in the mouth/throat will presumably throw this thing off. Sure the BACtrack S80 Pro is pricey, but during college I messed around with a bunch of cheap breathalyzers that were never very accurate. This thing is always spot-on, and well worth the investment. I haven't measured it against a police breathalayzer, knock on wood, so mirroring the sentiments of the thing's documentation I would caution against overreliance. I've used it for a month now without having to change the battery. We marked peoples' personal mouthpieces with colored sharpies at a party so that people could have their own without being wasteful. They also wash just fine, so I can reuse them for the next soiree. The instructions are crystal clear, you have to blow for a sustained ten seconds or so, this is very easy to explain even while intoxicated. A caveat: super inebriated people might vomit when trying to take a deep breath/blow, so prognosticate and monitor accordingly. We lost the carrying case, but it was handy when we had it, with a space for a spare battery and a dozen or so mouthpieces. Comment with any further questions, this is a big purchase for something that might seem like a novelty, but one that I heartily recommend for fun, durability and utility.

My husband and I had two drinks and tried this out an hour later, also adhering to the 20 minute wait time: No food, no alcohol, no smoking, not even water. We both agreed that neither of us would have driven feeling like we did, even though we were technically under the legal limit. His was pretty close to spot on according to an online BAC calculator, but mine was actually lower than the BAC chart. Not a lot lower, but enough that there could easily be a difference that could put somebody over the legal limit on a different device. To be fair, the safest practice is to drive only at 0.000. Which is exactly what the manual that comes with this device makes very clear. It will probably suit our needs, and it's easy to use, even if it's pricey. My smart aleck husband tried to cheat it. He refused to take a deep breath before blowing into it, and it definitely let him know! I made him do it 2 more times until it gave us a read. I mainly bought it for very early morning commutes after an evening of drinking. Mainly for me, since I'm a woman, and alcohol likes to stay with us longer. We never plan to skate the legal limit by going out, having a few drinks, and driving on .077 or some nonsense. And I wouldn't recommend anyone else do so! If it breaks or needs recalibrating obscenely early, I will update my review. But so far, so good. Getting a surprise DUI on the way to work sounds like a money-sucking nightmare, so why not not head that whole disaster off at the pass? Especially since the holidays are coming up, and we all know the revenue chasers are particularly hungry this time of year! Edit: Bumping this up to 5 stars, as it is well over half a year later and well over 200 uses later later and it is still very accurate and has not required me to send it for recalibration yet. I'm very pleased with this purchase. Edited October 2023 Had mine recalibrated a few weeks ago because it seemed to be taking longer to give a read (but still accurate after hundreds of uses). It's working perfectly and quickly again. Thanks, Bactrack!

Had to use this for a year before leaving the hose...It does work and I am sure it saved me further consequences. Highly recommend

So-- I'm returnig this because... I couldn't ever get a reading. I wantd to prove to my family my sobritty. Too long of a story here, but I don't drink, but (have been accused, etc.. none of that matters. I want to show, and prove my health state. It didn't work-- as in, it just errored out. I prolly got a bad device, sure ok... its going back. I just didn't work-- not like "oops your 1000% wasted or 1000% sober" it just errored out. And-- for me, its personal. So, this really failed me, in ways that are beyond the cost. So-- I can't recommend it. Not now. And I'm happy to re-review (But I'm not paying for it, so-- ya, vendor... send another for redemption)... but for me, and yall can read my other reviews--- this one was personal...and it failed... BADLY. On the "plus side", the unit was clean, all turns on, etc.. but it just ... literally didn't work, like--- at all. And I'lll be honest here, I've had to prove myself for a long time, I hoped this would help me show that. instead, it embarassed me--- that cost me more than the price of the product. God bleess, and goodbye. I want to say, I'll give the seller the opportunity to replace,etc and re-review. and I'll update this as is appropriate. I have to update this. I wasn’t happy with the product, and that’s fair… stuff happens. However— I have to commend their customer support. Honest, friendly, and happy to refund or make it right. In the most sincere manner, professional. I was impressed. Did it work for me? No.. maybe shipping broke it? Not sure.. but they 110% too care of me. Beyond impressive compared to most sellers. Even if this wasn’t the product “for me” or whatever— seller is 1000% solid no bs…. So, whatever they sell, I have full confidence they will make everything right… that’s rare today folks!

This product worked for ~200 reads. I sent it to calibration through BACtrack and they emailed me a week later to let me know that my unit had failed calibration. BACtrack Solution to my problem: Refund the calibration charge, as a courtesy (a given). Send the unit back to me as well as a $40 coupon to purchase another unit from their website. My problem with their solution: 1. The battery is rated for ~1500 reads... the unit itself isn't operable after ~200 reads. 2. I paid for a unit that could be calibrated for this very reason 3. Why would they charge a calibration fee for a unit that can supposedly be calibrated, but can fail calibration at the same time? Shouldn't they be able to re-calibrate so that it passes the specifications? 3a. There is obviously a quality problem here. I hold them responsible just as I would hold Apple responsible to replace the faulty chipset on my MacBook when it was found to be faulty due to quality (which they did). How many people actually send their breathalyzer in for calibration? Well I calibrate all of my measuring tools because I have been exposed to highly regulated pharmaceutical labs that run devices requiring calibration on a monthly or even daily basis. If BACtrack can't identify this as a quality issue and honestly address it, why would I trust them to let me know when I am blowing over the legal limit? Would you guess that your device isn't going to pass calibration after 200 reads? Would you keep using it knowing that its not guaranteeing precision or accuracy? Probably not. My proposed solution to BACtrack: Send me a new one and keep the broken one, as a matter of ethical customer service decision-making. If you can't guarantee quality after 200 reads, then stop telling people that the battery will last 1500 reads. If you can't build a device that can be re-calibrated, then don't charge me for calibration. My bottom line is that I either get a replacement from BACtrack, or I purchase the Trace from Costco and leverage my membership guarantee every time it doesn't pass calibration. I've wasted enough time writing this review. Get your breathalyzer "calibrated"... more like "validated" soon! It's a fool-proof way of guaranteeing that the breathalyzer is working FOR YOU and not FOR BACtrack's pocketbook. ***UPDATE*** I spoke to BACtrack customer service on the phone and here is what I got. The units are expected to last anywhere from 3-5 years (time dependent not based on number of reads). I have owned this thing for nearly four years. I'm very disappointed with BACtrack's dishonesty when marketing their product as being used for 1500 times on a single battery cycle, when customer service clearly states 3-5 year lifespan (maybe print a "best by" date???), even with "calibration". I suggest they change their verbiage from "calibration" to "verification" soon. Their calibration service consists of reading the device at high, low and mid BAC standards and comparing it to the acceptable range. There is no method of calibration, just verification. According to their customer service, this is a common occurrence after owning the device for three years. At least put an expiration date or some sort of specification that lets your customers know about this or else you'll inevitably have blood on your hands. For example, imagine an AED chest pad or battery doesn't have an expiration date. If it fails to properly operate and there is not safeguard or printed date, then good luck to you buddy!

Pretty cool. It’s teaching me how to tell how much I’ve had. But I will still rely on the machine for accuracy.

OK let me just say the obvious - don't drink and drive - good, that is out of the way So I purchased this device after being stopped a few weeks back by the local gendarme. I had been out to dinner with a co-worker, had a few glasses of wine, and was heading home, when we were stopped for speeding. It happens. I was asked to exit the vehicle for field sobriety tests, and for a breath sample - now, most people know a handheld unit by the side of the road is only an indicator, not something admissible, but I blew anyway, came a hair under the .08 limit (.058 actually), was warned I could be charged with impaired operation, and generally just had the shit scared out of me. Ultimately we were let go. It got me thinking - I always considered these to be for someone intent on beating a DUI by measuring their BAC, but I never thought of the multiple times over the years, I simply lost track of that shot of bourbon, or that glass of wine - not out to get buzzed, just out perhaps after work for a few with friends, and how many times apparently, I may have been close to or even over the limit without even knowing. Scary stuff - and to those who say 'even one drink is too many', I agree, but the reality is, most of us do it from time to time, so I'm not playing the moral compass here. So everyone online, including online tests by enGadget, Wirecutter and the rest kept mentioning this slick little unit. After much research, I grabbed one, just to make a determination of where I was heading out - the unanticipated side effect, was it also made me conscious of my intake. If I wasn't comfortable, regardless of the number, I always had Uber (which I love anyway). I paid 129.00 for the unit, and factored in calibration, which should be about every 6 months based on usage, and the fact it seems to be a popular thing among my friends, curious as to where they stand before leaving. AGAIN, it is just a reading - your BAC will continue to rise as your body processes alcohol on the way home if you have had a drink, so use it to make good decisions, nothing more. SO ... things I like about this one? NHTSA and DOT approved, single button operation, long battery life (1500 reads if what I read is correct), fuel cell sensor, compact, and fast - once you blow, you get most readings in 5-10 seconds, and can do a follow up test almost immediately. The screen is big, backlit, and easy to use - and one thing I NEVER imagined? It's a great conversation starter - not to be shallow, but the girls will come to YOU, and it's fun to talk to them about it - oh so blame me! lol I'm single. Other things I like? the great little padded carrying case which holds everything you need, the supplied mouthpieces, and yea even silly things like the fact the give you a pair of Duracell 'copper top' Batteries and not some cheap throwaways. If there are CONS I haven't seen them yet, but it's early - like anything else, this is just a tool nothing more. It arrived well packaged, and the next day from Amazon, has a one year warranty, and is consistently rated the best in its category. One last item of interest ... I showed this to my co-worker who was in the car originally. She reached into her purse laughing and ... pulled out an S80 (apparently she has owned one for the past year). She loves hers also. So in closing, if you are buying one because you like to go on benders, it's probably a better idea to re-evaluate why you go out, and/or download the Uber App to your phone - If you are wondering where your BAC is after dinner, want to check your teens, have an interlock in the car and want to avoid being locked out, or need to verify 0.000 each morning before going to a DOT job, this is the unit. Enjoy. Cons? I haven't found one yet, but give it time -
