I just had one of these for my Birthday, it's a very nice cover which is quick and easy to fit. I like the hinge design and the way it has magnets to hold it up in two angled positions. The grey colour won't appeal to everyone but it looks quite stylish.
The cover also folds back quite nicely without pinching for use of the tablet on a JML Pill-O-Pad.
Because it's genuine Samsung the cutouts for buttons, sockets and the camera are absolutely spot on of course.
So while there are cheaper third party covers, I would highly recommend this genuine one instead
