What customers say about "Key Specs"
BACtrack S75 Portable Breath Alcohol Tester
  • This breathalyzer is one of the best deals for a high accuracy machine, a much better deal than the lower-tech units on the market for similar prices.
  • After several tests on several different occasions using not just myself, but a few friends as well, I have concluded that this is not only easy to use and carry around, but it is also by far the most consistently accurate device vs. police issued that I have used.
  • I am very pleased with my purchase of the S75 breathalyzer. I have cross-checked it with a police breathalyzer and was amazed at its accuracy and that the general public can get their hands one for such a reasonable price. Highly recommended!
  • I don't think it is as accurate as the company describes it to be. It says that it's accuracy is +/-0.005 @ 0.050, 0.100, and 0.150 %BAC but it can differ by 0.01 as my friends blew a 0.16 and then a second time yielded a 0.17
  • It was ok at first but results became out of possible range within first 6 weeks, I tried to follow directions but apparently it needs recalibrating often.
  • Good scare tactic for "young adults" not sure on the accuracy. Ease of use is iffy.
BACtrack S80 Professional Breathalyzer Alcohol Tester
  • Not only does this tester measure to the thousandths place, it also has features to ensure the most accurate measurement possible
  • It is easy to use and very accurate plus fits on glove box nicely. Been using it for years now and would highly recommend to others.
  • Simple to use. Very accurate. (Compared accuracy to two other devices by other manufacturers.) Super fast results. It functions perfectly. So simple a drunk could use it.
  • I think the most important aspect of a breathalyzer is accuracy and this device is one of the most accurate you can.
  • The only downside is that this product's instruction manual recommends re-calibration every 6-12 months without any place to mail in the unit, or instructions for how to do this. I'd be worried about accuracy in the long run.
  • Okay product to make you think before driving but the accuracy is questionable. With a price tag like this has, I would go a different route.
  • Not so sure on accuracy. But a cool tool to get an idea of where your at with B.A.C

What customers say about "Features"
BACtrack S75 Portable Breath Alcohol Tester
  • Sleek, ergonomic design.Portable so you can take it with you wherever you go.
  • It has a very fast response and while I cant be positive of the accuracy, based on my size and amount consumed it appears to be dead on. This makes any indecision on driving confirmed.
  • Sure you pay a little extra...but this thing has a fuel cell in it. Same as what cops use and what they install in your car for a breathalyzer.
  • Press start, wait about 15 seconds, blow for 5 seconds, wait for 5 more seconds and get a reading - it really is pretty simple to use even if you have had a few to many!
  • The unit worked acceptably well until it went out of calibration. In order to recalibrate, surprise!! You have to mail it to California with a $20 fee.
  • This unit did an excellent job initially, but failed after about a year of very light use.
  • It was ok at first but results became out of possible range within first 6 weeks, I tried to follow directions but apparently it needs recalibrating often.
BACtrack S80 Professional Breathalyzer Alcohol Tester
  • Good product and features. You can program the unit to require 3, 5, or 7 second breath samples (the longer, the more accurate). Mine is set to the default 5 seconds and seems to be accurate to within .01% BAC.
  • This unit uses fuel cell technology, which is absolutely what you want. The number of samples that can be taken before requiring recalibration is impressive, and the recalibration only costs $20 (I have not gone through this process yet).
  • 3 digit read out is a good feature. Fast, dependable, and appears to be very accurate.
  • Battery stays charged for a very long time and this is an indispensable addition to my car's glove compartment.
  • One feature I would have liked is a little memory, which it doesn't have.
