Since Tesla no longer offer glossy seatback for Model X, I am trying to get after market options and i found 2: 1) Tesla Model X Carbon Fiber Seatback Set Expensive. The installation video is not very clear. Is this just snap on or replacement? how hard or easy to do it? since 2 people doing it in the video so I don't think it is easy 2) R-Zentric Products by Revozport This one is cheaper and it is just snap-on and look easy to install. But, is this durable? easily get a ding or scraches? If you have purchased and installed one before, please kindly share your experience. Thanks!
