The Forma cover feels quite nice. In contrast, the Aura One cover feels like "elephant skin".
However, I AM concerned with the durability of the cover when used folded. If you look at this review (link below), you can see how the "lip" is folded over to prop it up. I'm concerned with the creasing and wear/tear from this position.
