BACtrack S80 Breathalyzer | Professional-Grade Accuracy | DOT & NHTSA Approved | FDA 510(k) Cleared | Portable Breath Alcohol Tester for Personal & Professional Use

I’ve had this device for about three years. I even had it calibrated once. It is pretty expensive, but is so much better than the cheaper ones I’ve had in the past. The cheap ones would fail to give a proper reading and showed 0.0000% when I KNEW that wasn’t the case. They would fail time after time until I finally gave up. This unit gives very reliable and repeatable readings. If you’re going to use a blood alcohol meter, you might as well use one that actually works.

This product is the best. Hands down. Accurate, precise, valid, and consistent. Definitely worth the bang for your buck. I trust it... l still need to figure how to recalibrate, but so far so good. Have this product for about 6 month with good use.

Works as described, never can be to careful!

Works good but you'll have to get a calibrated if you use it a lot

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 reason3. 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!

Bought as both a tool and a party game. It works well, but you have to not drink for several minutes or it won’t work. I had half a beer, just took a drink before trying and said I was at a .21, almost 3 times the legal limit. Apparently when alcohol is fresh on the breath it reads too high. Don’t drink for a few minutes before blowing and it’s accurate.

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.
