Bought 6 of these for myself and my family. We have one in each one of our cars. It is a very useful item since we do enjoy our cocktails. Plus when my sons have had parties they would use these to ensure their friends were safe when they left. I feel it has saved his friends lots of money and embarrassment.
Our sons have been using their Breathalyzers for abour two months. Each one of them has had to call us, or take a cab because they were over the legal limit. They both said without the Breathalyzer they would have gotten behind the wheel and drove home.
Seems like for the money, this is the most flawless device out there. It's small and is very stylish. Comes with several spare mouth pieces. Has one button, so no matter who drunk you get you'll be sure to remember how to use it! The only downside that I have found is that after several consecutive uses, the results tend to become less accurate.
I traded the S30 for the Element and I am so glad that I did. The Element is worth the money and is accurate. After my first use, I tested to make sure it accurately read the BAC after each hour that went by after my last drink. I watched the BAC decrease as it should by .015 per hour. What I cannot verify is if the initial reading was correct. However, based on the alcohol that was consumed and the length of time during consumption, the reading did make sense. I'm very happy with this unit and highly recommend it.
