How to recognize if your interface is original or from China. I bought in Poland and I paid a lot of green color
What interface did you buy?
I tried several cheap and expensive adapters until I bought Polish Viaken STN 2120 and it's the best green interface. Upon updating the firmware in the STN2120 chip to v5, it is fast, free of errors, freezes and crashes.
