My Gecko Slimfit cover arrived today, and it's everything chromedome said. It's very sturdy,
extremely sturdy, the magnets are in the right place for the sleep cover to work without flipping pages as some have had. It's a perfect fit like a glove, it doesn't really increase the size of the reader, just the thickness, and of course the weight.
I wish it had more of a matte finish to it, it's a shiny textured finish, but that's really being nitpicky. It's really well-made and I'm very happy with it.
