My
Fintie smartshell cover (navy color) arrived yesterday. Love it!
It's reasonably light, well made and the auto-wake/sleep works perfectly.
I have the Amazon origami cover, which works well too. I'll keep the Fintie because I prefer kindle covers that open like a book (left/right vs up/down).
Edited to add: The navy-colored Fintie cover is beautiful, it's actually a darker blue than the photo on Amazon depicts.
