DC advance - with this breathalyzer I am completely satisfied!
The service is a bit more complicated, as the AV-MG04 - but for the readings seem to me to be much more accurate and reliable.
Examples:
After consumption of a Hefeweizen (0.5 l) and 15-30 minutes waiting time always shows the FiT178 a value from 0.27 to 0.33 - which seems to be a reasonable value each mine.
After 2 wheat within 90 minutes I reached a value of 0.47 - also ok
If I repeat the measurement after 15 or 30 minutes, the test result is always lower than previously.
A reading of 0.0 is reached again only after at least 90 minutes abstinence (when AV-MG04, this could already be the case shortly after the consumption of alcohol)
In all previously performed measurements I had the feeling - yes, that may be right!
(Since I have not a calibrated comparison device, I have the results by means of calculations on [...]
However, one must necessarily the time to wait 10-15 minutes and should hold even better before rinse your mouth.
Shortly to use: It's not hard at all - if one has read the manual carefully and carried out already 2 to 3 measurements. But pressing button 1 once, then button 2 once, then press the duration piiieep button 2 and blow five seconds - that's more complicated than the AV-MG04. Also to switch off you always have to wait until "Alko" appears - but it is not difficult anyway.
Therefore, I also give full credit - because the main thing that measurements are traceable!
And that actually seems to be the case with FiT178.
