Query: Worst purchase yet

OK, maybe I'm just being dramatic because I'm pissed. I got the right adapter, plugged it in, and it worked (just meh, though, nothing worth complimenting). I pull it out after about a minute of a test, and a piece of it had broken off and lodged itself in my headphone jack. Now my computer thinks that there are always headphones in, so the speakers won't play. Also, after I pulled it out, it separated from the plastic shell into a bunch of components. Obviously crappy quality, don't waste your time.
