I had someone else's Blues in my possession from the same source, and they were also in the same condition: all had solder on the pins, some pins were twisted/bent from desoldering. That did not bother me too much, based on the low price, but most of the switches did not click properly (either no click or the click was augmented). Some switch stems did not move freely in the housing and would stick a bit.
It would be nice to put it on the sale page description that these switches are not new or else some other way to describe their exact condition.
