I was going to buy one but thought better of it. One of my friends did make that mistake and, after using it for a couple of weeks, said he thought it had been a waste of money and offered to give it to me. I declined.
I own an iPad and I bought a Smart Cover for that. I like it because it's well made and importantly, stays neatly shut due to the magnets. If the S-View cover snapped shut and stayed shut, it might have been good but it doesn't so it isn't.
I also thought they were grossly over-priced considering what they are. All in all, the S-View cover is a miss not a hit.
