Well your experience is not relevant to mine. My device didn't need a "thorough" test, literally turning the device on and testing its most fundamental functionality would've told them it's broken. No, mine did not have mechanical or sensitive parts like this that could've broken along the way, or anything like that. These were very clearly something they never tested. And no, they weren't $5, they were quite a bit more. And these were very clearly priced just enough below the actual working ones to entice you into buying them. Of course it doesn't seem like you want to to believe me no matter what, which is fine. I'm not sure what the point of arguing to discredit my experience is. It just drains our energy to no end. I know what I see, and you know what you see, and that's basically all it is.
