The design of the cover is excellent, looks great and feels great. The only issue I have is that the magnets used to keep the cover closed, interferes with S pen's accuracy. When the cover is opened, the magnet clip is moved behind the screen on the right, this causes extreme interference with the S-pens responsiveness/accuracy on right side of the screen. Although it does not seem to do permanent damage (right side of screen works fine if magnet is moved away or the cover is removed), only time can tell whether it will cause big issues over the long term.Furthermore, most people find it hard to pull out the S-pen.
If it was not for the magnetic issue I would give this case a 5/5, so do make sure you consider what is more important to you cheapness/style/design vs. efficiency/user friendliness.
