This is a great product and really worth the money.
This is a great product and really worth the money. It is good to recognise that it is only measuring alcohol on the breath, not in the blood, but that is enough to guide you into learning about how to behave. If you test yourself just after taking a swig, you will find that you can easily be over the limit: if you wait 20 minutes, it will give a much more reliable reading, but if you use this alcohol tester sensibly, you will try testing yourself at 30 minute intervals during and after an evening and watching to see how the reading steadily declines
