Mac-Valve Maestro!
Used just a few times , as we know doesn't translate to good, great , or perfect condition.
Just means used a only a few times.
In this case I think you made the the assumption they wanted you to make.
Was it even new when they got it?
Just playing devil's advocate here.
There's A LOT of people I wouldn't buy an airbrush from even if it were " used only one time"
Ebay's went through ALOT of changes throughout the years, to get rid of the guys/gals that think it's a Yard sale ad, and can lie and weasel sell their junk as if it were new. They have categories for a reason. If you're not sure, then sell it as "for parts only". But "used" under Ebay rules, means it's supposed to work.
But that don't mean there aren't just as many scam buyers. Imagine a guy orders a Micron, changes the head unit to one from a Master, and sends it back saying he changed his mind, or it don't work. Imagine how long it would take for that to ever be discovered. That crap can happen all over the place.
If I pushed the issue, I may actually get a full refund, but I don't care at this point. Nozzle and needle are already on their way... slowly.
