no one can say how durable or what quality they are are. no one on here has any access to warranty rates or quality control signmas. any posts anyone makes can only be there personal experience and your experience may vary. i would put the "quality" thing out of your mind and instead ask about warranty policy and peoples experience with returning them, or ask shops who sell them how they handle any issues like that. most companies are trying to balance making a good product with being profitable, and most brealize you can't hock junk and stay in business.
