I have had the Skinomi on now for two or three weeks. I don't really know it is there except for one thing: When I open the case I use for the Nex 10, it has stitches that press against the screen. I can see the indention's from the stitches when the screen is off, but when you turn it on, you don't see them and they go away after a while anyway. My other cases do not do this because they lack the stitches. Don't know whether this is a case issue or a protector issue.
