Weird.  "Bad" how?

They leak.  I replace dozens of them a month, depending on whose kit I have on the bench.  There's a particular make and model of radio that goes utterly deaf because three little 0.1μF SMT ceramic caps go leaky and screw up the biasing, although I think I've got pretty much all of them replaced now.  Hopefully they'll hold up for another 10 years and then they'll be someone else's problem.
