That would be really funny if you got your own returned covers in the warehouse deal.
I am a bit upset that they went down in price so much right after I got mine, but I guess it is what it is. I don't use it as a stand, but I did try just to see and it works fine on that too. Are the magnets as strong as on the Oasis1? No. But they seem strong enough to stay on for what I need it for. Since I read out of the cover anyway, its just meant to keep it protected while its sat down somewhere. Screen mostly. I am not concerned about anything happen to the back its pretty strong.
Those 3rd party are too hard to get it out every time I pick it up and I like the wedge to read. Which isn't there on the covers either once you fold back the cover to read. But its good to have some options.
I need it to be as light as possible to read with as it is heavier and bigger than the old Oasis. So I could never read with the 3rd party covers as they said to be heavier than the official. That would be uncomfortable for me and my hands.
