This is a good case made with nice materials. it offers a nice fit and buttons are easily usable. it comes with a clear screen protector and has a belt clip so you can carry it more comfortably. it is just a little bulky, but nothing to worry about if you plan to carry it in your belt, hand bag or hands. it could only fit big pockets, though. my only serious gripe is about the inner seams, they are very rough and could scratch the surface of your player. yes, Zen Vision:M's have very soft coating and this could leave marks. anyways, you really should consider getting a skin for your zen (Best Skins Ever) in any case. This is a very good case overall.
