BOOM!

Also, there is apparently a thriving business by certain Chinese vendors in 
VERY fake transistors, which look like "real" transistors, but are, in many 
cases, 2N2222s inside a much larger, more robust "case".

MRF-485 comes to mind.

This reminds me of the millions of defective electrolytic caps they made and 
sold which were used in thousands of computer motherboards a few years 
ago.

And their very marginal 572Bs....which aren't... really.
