The unit is located in a small bag that is also helpful if you take somewhere wants to take it with the device. The bag including device fits well in many normal handbags.
In the bag you will find the alcohol tester, some mouthpieces (wrapped in plastic), batteries and instructions. The manual is short but good. We know what to do and also on what to watch.
The handling of the device is also very simple. Even if you have been drinking you should still hammer out (have the but now often tried). It turns the unit, waiting for that one must blow into the mouthpiece (look at the display) and waits for the results. What you always have only seen on television, for example, in some reports, you can now try it yourself.
The measurements should be very precise and make sure it stays so you should make the device regularly (so after a year) by the manufacturer recalibration. Is not nothing but if you really regularly used not certainly wrong. To what good is a alcohol tester the wrong Bess displays data.
Whether you need it must each decide for yourself but I'm excited. The alcohol tester is satisfied and also comes very handy for a home.
