I just received this winder today. It was packaged in multiple layers yet still had some slight damage on one of the corners, but it's barely noticeable. Obviously, I can't speak to it's durability, but all the motors seem to work well. I like that you can individually control each of the 4 winders to its own setting. My only real complaint about this winder is that there's no pull on the glass so you have to use the key to open the door, even if it's unlocked already. At around $200, this winder offers a lot for the money when you compare it to other brands, so it feels like a good value. I'm happy with this purchase.
