Ratings & Reviews+

BACtrack S75 Pro Breathalyzer is rated 4.6 out of 5 by 33.
Rated 5 out of 5 by from Highly recommend for any social drinker I highly recommend this product for anyone who drinks - anywhere! At a party, at dinner, or any other social function. And it is also excellent for checking guests' BAC before they leave your home (extra mouthpieces included, and can always purchase more). You'd be surprised how many people think they're all right - and they are not (me included)!! Also, when it comes time for a re-calibration, BACtrack gives you excellent service. Pay a minimal fee up front, return your BACtrack for re-calibration (pre-paid postage) and they mail it back to you postage paid - hassle-free service! I've recommended the BACtrack S75 to a couple of friends of mine who have purchased them and have thanked me. It's just that little bit of reassurance every social drinker needs before getting behind the wheel of a car!

Rated 5 out of 5 by from Simple and easy to use. I bought the BACtrack S75 Pro Breathalyzer from another vendor because it was less expensive. 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.

Rated 4 out of 5 by from Illuminating experience In Quebec, BAC limit is 0.08. In Ontario, it is 0.05. I now live in Ontario. I was surprised to see how I was affacted by alcohol at 0.08. Even though it is advised not to use it to that end, I use it to make sure I am under the BAC limit before driving a vehicle. I don't rely exclusively on the reading but also, obviously, on how I feel. The only drawback I have found with the device is that the manual says it can be damaged if you don`t wait 20 minutes after eating/drinking before using it.

Rated 5 out of 5 by from Good product It cost a little more than I wanted to pay, bu then again, if it saves you or a friend or a family member from an accident or even a ticket just once, then it pays for itself. I think it is a very good investment and more people should be carrying these around. The readings are quite consistent. Usually blowing twice in a row will result in values within +-0.001. I have plotted by BAC dropping as a function of time for different initial levels. It's very interesting to see how quickly my body processes alcohol (and informative, as it enables me to predict my BAC more accurately). Mostly, I just use this device for fun, but at the end of the night it serves the dual purpose as a safety device as well.

Rated 4 out of 5 by from Great This is a very good product, highly recommend it. I've had several smaller products but this by far was the better.
