Cute Party gimmick, but no longer!

After extensive test operation is now clear - leave under any circumstances on the device to determine its ability to drive. We have the equipment some weekends long - even on very "liquid" Home Parties - tested, and the results were very arbitrary. Partially a value of 0.5 per thousand was spent for a beer, on the other hand with people who could no longer stand alone, a value of 0.3 per thousand.

For the price, it is therefore a nice gimmick for nightlife, but please if you go simply by car nothing to drink and not rely on such breathalyzers ...
