Lay's!


Apart from the made-in-China-under-supervision stuff.

They do like to sell fake MAX3232 via ebay and Amazon, which go into
latch-up when sneezed over at the wrong angle.

And they really like to sell fake power transistors at Chinese ebay.
They misunderstood the meaning of the word "die" in terms of necessary
ingredients, so that's what they do when trying to operate them at 1/10
of the spec'd power to dissipate. (cutting them open reveals small
signal BJT die - hence the unbelievably high hfe for those, dead giveaway)
And that's what I witnessed myself as some hobby electronics DIYer doing
this on a couple weekends a year.
I'm sure there is far more out there.
