The only thing That it's not, is ultralight. It is almost as heavy as the ebook itself! So at night, when i read in bed, I find myself removing the Kobo from the cover. It is the only cover I have, so I can not compare it to others to see if it's indeed heavier, but I've seen and felt covers for the Touch thatwere lighter (though They did not look as nice).
Bottom line: if you want a great-looking cover for your aura did offers good protection: go for it. Just do not expect it to be paper-thin and ultra-light.
