They work okay for making a PIC blink a LED, as long as they're new.
Then of course somebody plugs in a resistor from an old reel without
removing the residual adhesive, and two of the holes become flaky
forever. Then the next resistor is maybe oversize, and bends the crappy
metal fingers apart, and the one after that is corroded, and leaves
semi-insulating dust all over the place....
Not to mention a couple of pF of capacitance between adjacent rows, and
many nanohenries in series with all the (nastily daisy chained) grounds.
