coils, clearos, and cartos, etc. can't be QC'd by the stores since those are sealed and disposables to begin with, but mods, like mechanicals for example, can be QCd at the store before it's sold to consumers. It's one way for the store to save themselves the trouble of complaints. One less trouble that could be eliminated.
Word, you're completely right. I can't say more than this, but we emphasize trying it out first. If sold and issues arise, 30 day warranty. I can't go further than that without breaking forum rules.
