I don't like their tactics. Z1 seems like they mean well, but just can't get it right. It's like trying soooo hard at school class and still flunking. Something wrong and they can't or haven't found how to fix it. They have some good people, and some not so good. And as with anything, communication is lacking. Ordering parts from them is not the problem, it's their mechanic service. Don't get me wrong, I would trust Z1 before before i had doubt with anyone else. They just wouldn't be my first or second choice.
