I started using this device when I was drinking and not driving. I was trying to gauge what I blew after 2 glasses of wine or after 3 beers. So I had an idea of my BAC levels in relation to consumption. What I have found is that the read out is always different. Perhaps its different becuase of what I ate or what time of night I use it. I have only had it 2 months. Between myself, my friends and my family we have used it about 80 times. I think it has to be recalibrated. The read out seems to vary between everyone drastically. I understand men and woman process alcohol differently. But even the same person seems to have different read outs from night to night. I have recommended this to friends - because you are still getting a read out - and its better to know your BAC than not to know and take a risk by getting behind the wheel. Even if each night its different - atleast I know what my BAC is for that night. I will be sending it in for calirbation in the next few weeks. And I will continue to use it.
After having the ability to reliably test my alcohol level, I can't imagine giving it up. I use the S80 any time I drink and plan to drive. I now have total peace of mind knowing that I am not impaired and below the legal limit. If I am above the limit, I don't drive! Everyone wins using the S80. BTW-This is the first product that I felt strong enough about to write a review. For you, your family and the rest of us...buy this product if you drink!
This unit is fantastic! Reliable, accurate and worth every penny. All of those benefits coupled with the fact that it could save you thousands ... Can you afford not to have one?
The product works well and is easy to use. You must wait 20 minutes and drink water to get a good result. You can have your first drink and blow over a .08 if you don't wait.
Really love the product, and can rely on it. gives accurate readings and easy to use, i should have bought this long ago, and know some friends will do it now too.
I use this product if I go out for dinner and drinks. A very nice size to hold in my hands. The S80 is very easy to use. I cant find anything wrong with the S80.
I use this to be sure that I don't get a violation on my interlock system on my car. This device is way more sensitive and accurate than the one on my car.
