Materials: The cover is high quality, well made, which you/I should totally demand from a cover/case from the manufacturer. For a folio style, it is very comfortable and fits correctly. It is a thinner folio style cover; I was worried at first that it might have been too thin, but in the end, I think for carrying in a bag or reading in the park, etc. the cover's protection is suitable. If you're taking it camping or something where the chances of damage are higher then you may want to consider a secondary, more rugged case and screen protector.
Attachment Method: This brings me to the attachment method, which is where I had my main issues with the case. To utilize the folding stand the only real viable method of attachment is through magnets. This worked fine for setting the tablet on the counter or a desk, but the method isn't completely stable if, say, sitting in bed and you have to pick up the tablet/case and move it. It was here that I had the table detach several times and fall off and onto the bed mattress. This case is very secure when sitting on a flat surface, but if you have to move it you had better grasp the case and table together before doing so or you may end up dropping the tablet. Ultimately, this is why I returned the case. After having the tablet become detached several times, I knew I was begging to damage it, which is definitely not something I want to do with a $450 tablet.
S Pen Position: Some people have misunderstandings concerning where to put the S Pen. There are two possibilities. You can either use the two magnetic strips on the back of the cover. I was a bit weary of this method. It seemed to be begging to lose it by falling off. I opted for method number two which was to clip it on the spine of the cover. This spot still isn't ideal as the pen is exposed on the outside of the case, but I didn't fell it was going to fall off the case either. Samsung, would it really have been so difficult to make a pouch to slide the pen into?
Overall, if you are transporting the tablet via a secure method such as a backpack or computer bag, etc. and you are using it in a responsible way, on flat, secure surfaces, then I think the case is an OK purchase considering it is made of nice materials and the S Pen attachment can be worked with. But, if you are going to be using this tablet for media consumption and the like on a couch, bed, or outside on uneven surfaces or your lap, I think you need to at least purchase a secondary case and screen protector, something more rugged. This case is simply not built for that kind of usage and if you try to utilize it for that then you are begging to damage it.
YMMV. I think Samsung can do better than this given they want to charge $50-$60.
