I've had a few fakes or knockoffs -- mostly low-cost electronics that I didn't care too much about.

But one of them was an AC adapter for my laptop :|

After I plugged it in, my laptop smoked. Well, more like sizzled. The manufacturer replaced the motherboard for me. After it happened, I examined the two AC adapters I had (real + not-real) and they were virtually identical except for some font and mark differences.

That was enough for me to change my shopping habits wrt to expensive electronics and to start using review analysis sites for everything.
