Case in point: 2SC1969 and 2SC1971 They're very well known power RF
transistors for HF and VHF which are not cheap, but Chinese sellers offer
their fakes for less than 1/10 of their cost from reputable sources.
Chips such as the NE5532 are counterfeit too, whoever buys them from 
Chinese suppliers basically gets relabeled TL072s if he is lucky.

I can confirm that. Batches of cheap ICs/Transistors etc. are almost
certainly fakes, while modules and small devices usually do work.
I've bought amplifiers, testers, uC modules etc and never encountered
a problem, but try to stay away from active components, save for
those that are so cheap that faking them isn't economically
convenient anymore (LEDs, drivers etc).
