Nope....many clone have logo f and alps.... AliExpress is not good for buy component. Better buy on seller of ebay. I buy 1 analog xbox one 3,50 euro and work fine
favorshine is chinese factory. chinese rules for making fakes of domestic manufacturers is very strict - jail. so any favorshine analogs with F logo are genuine.
for alps- fakes have very awful engrave, and rotary discs have long grips.
all three orig alps and one favorshine orig. one on the right has fake pots
original alps engrave
