Fast delivery, easy to use ... the advance. However Messsungen led the first practice test to extreme deviations. After a fun evening I tested the device. Not to check about my driving ability, I could have so appreciate after about 2 bottles of wine (just for me ;-)). The more astonished I was at the first measurement ... 0.45 per mill - everything's alright ... This I did, however, hardly possible for ... Within 10 minutes I still led by two further measurements. The second gave 1.7 per mill and the third measurement 0.75 .... That is not even an approximate value !! If the units of police work the same way, then good night ... Conclusion: packing and send back. Too Bad ...
