I have the Cognac cover. I had one previously on my first 950, and it was excellent. It was durable and it looked and felt great
Unfortunately at some point they changed the way the silver "metal" is applied. It used to look more like brushed aluminum, and was very durable, still looked great after nearly a year. The new finish looks like silver paint, nothing like metal, and it starts to wear off in only a few days. I contacted Mozo about this and they offered a replacement of a different type, but never addressed any changes in the process. I have a zebra wood cover sitting in a drawer at home. You can see the state of my cover, and that was only after a couple days. It has been about a month now, and it is basically completely black on the corners.
I would have previously recommended the Mozo covers to anyone, but I'm afraid now I would no longer make that recommendation.
