It's a general observation that comes from seeing many pcb's sat (usually) on carpets both here and Ebay, and people telling us they don't work properly.
mmm if they've taken a photo of the pcb to show us when it doesn't work.. wouldn't it have already been broken before it went on to the carpet (or similar) to be photo'd?
I wouldn't buy anything off ebay that wasn't guaranteed against it being DOA unless I was buying it for spares.
In my work as an electrical/electronics Engineer working on trains in the UK
Working with higher voltage -- CMOS -- logic? You'd think the stuff used on trains would be a little be more rugged considering it's going to get shaken around, covered in crap etc.. A lot of stuff has protection against ESD up to 15kV or something these days.
Anyhow.. I would have said taking a soldering iron to the thing would have been more of concern.
