Key Chain Digital Breathalyzer

The holiday season is the season of parties and that means more drinking then normal and that can mean that you go over the legal limit and are not allowed to drive any more.

But how do you know you reached the limit?

This key chain can help as it is a digital breathalyzer and this little tool can help you find out if you need to call a cab and helps other on the road to be safer.

It can detect blood alcohol content from 0.00 – 0.40% by using police grade sensor technology.

So if you want to be safe while driving or maybe want to help you friends find out if they should drive then don’t wait and order your own Key Chain Digital Breathalyzer.
