  • Simple, accurate, and easy to use.
    Verified Purchase

    I bought the BACtrack S75 Pro Breathalyzer from because it was less expensive than buying from BACtrack. Same unit as pictured and demonstrated here. I tested it with my friends who drink and on myself while drinking. Interesting to see that the drinking guests and one who did not drink consistently read .000 while the rest of us had varying readings depending on after having a swallow and after the recommended 20 minute wait time. I have an Ignition Interlock device in my car and trusted the reading when the S75 said I was under the FAIL limit on my car and cranked it with no problem. It's nice to know your actual BAC before driving any vehicle and making sure guests are below the legal limit before they left my home. This will pay for itself and definitely keep me from ever getting another DWI again. Highly recommended. I like the front position blow on this model and it fits nicely in the velcro case with room for additional mouthpieces.

  • Do not buy - stopped working after 18 months.
    Verified Purchase

    I purchased this product about 18 months ago. Like most of the reviews state - it is a great little unit, worked every time I needed it and seemed to give accurate results. It recently stopped working, the unit powers on, counts, let's you blow, and takes a sample. However it quickly returns a 0.00 every time, no matter how much I have had to drink. It has been well taken care of, never dropped or damaged. Fresh batteries did not fix the problem. Overstock will not replace it because it is over a year old. I expect to get more than 18 months of use out of a product I paid close to $XXX for. Waste of money - look at other brands and sites with better guarantees.

  • Does just what I expected

    I was curious to know what my blood alcohol level was after a glass of wine. Now I know. The S75 is easy to use. Seems to be very reliable. I had a question about some of the options, and the customer service person was extremely knowledgeable and helpful. I use it a couple of times a weeks and of course, my friends want to try it out as well. I am glad I finally made the investment.

  • Best performing tester I have used

    I have tried many different breathalyzers in the past and happened upon the BACtrack units. I decided on the S75 as it appeared to be a professional grade device and I am glad I chose it. I have tested this unit many times as have my friends and its consistency was great. We cross referenced with BAC charts and now we have even more confidence in the results. This is a great tool to have. I now carry it in my car every time we go out for the evening. This is the first BACtrack unit I have purchased but will buy more for friends and loved ones down the road. Highly recommended.

  • Good Unit
    Verified Purchase

    Pretty accurate, may be off by a point or two, so add one or two points to the amount that displays. Great to keep in car or carry in purse. Don't leave hoe without it!

  • Must have
    Verified Purchase

    This is a must have. I unfortunately made a bad decision and got a DUI. I didn't realize what alcohol really does. Thankfully I didn't hurt anyone, I was just speeding and got pulled over. Now I make everyone blow into this before they get in the car to drive after drinking. My friends now understand what a few drinks really do.

  • seems so work as advertised
    Verified Purchase

    Easy to use. Need to wait about 20 minutes from last drink or food to get accurate measurement. If you don't wait or use mouthwash, the levels will definately be way off. It offers a reasonable way to make sure you have not overconsumed and give pretty solid guidance for any important and possibly expensive decisions.
