Even the device itself makes a high impression. It is handy and looks chic. The display is easy to read.
However, I have not managed to push out the specific tubes for personal use, either I did not have enough strength in the hands, or it stuck somehow. (I suspect the former.)
I have therefore taken the test with one of Aufsetzröhrchen. And showed how great this device is.
While I had the problem with one of the other models that now and unrealistic values came out or I constantly got error messages, it worked with this device right away. When blowing displays a clacking noise that will be evaluated. The measured values seem to me realistic.
I myself drink alcohol anyway, if I have to go, but on the Westphalian family celebrations are some candidates who are convinced, even after a few beers and Short still being able to drive. I could with this device disabuse some were quite shocked that her blood alcohol content was twice as high as the estimated by themselves. Then some cars are stopped and ordered some taxis.
The machine can be dropped also to determine how fast you degrades alcohol, this is individually different. A nice touch to show young people where their limit is.
It would be best, of course, no one would drive a car if he has been drinking alcohol. But for those who do not want to miss at least the welcome champagne and wine with your meal, this unit is valuable to determine when the alcohol is removed.
This device can therefore save lives.
