This won't help OP (sorry to say), but I ran across this thread before ordering my own depo replacements. Because of what you dealt with I ended up ordering off of Amazon rather than ebay (pretty sure its the same seller though), and the first thing I did when they arrived was checked the adjusters. I've never returned anything through ebay but Amazon has always bee stupid easy so I was more comfortable with that route.
No help to OP, but I at least wanted to thank you for pointing out a potential issue that the rest of us could learn from.
