Hello guys, I’m new at dashboard business in I need some advices, if anyone can pleas help me with some answers. I will like to work with VAG group dashboards, recently have I buy the VAG K+CAN COMMANDER 2.5 and VAG COMMANDER 5.1 both are clones from china. Can anyone give some comments about reliability of these interfaces? I have heard a lot of bad comments at odder forums.
