added I was initially a little skeptical in relation to this equipment.
Well I must say that it is inferior to the optical device similar in almost nothing.
Fast ..... the live data recording does not exist to the extent.
But that does nothing, because I do not need such a thing.
It reads and erases all DTC's (error).
Reads all relevant information, such as air, Temp., Etc
Is easy to use and (most importantly) in German.
Has an easy to read illuminated color display.
The support of JCAsoft is good and without problems.
There is an English manual and software updates.
Conclusion:
The price-performance ratio is absolutely convincing
