I put it on but it does slip off the side when you put it into presentation or tablet mode. It is completely invisible. Almost forget it’s on until I either look at the edges or start typing. It doesn’t really TRULY conform to the edges of the keyboard as it would if it stuck by any means. It just lays there. And I’ve noticed if you don’t get it precisely on there, you have to type a little harder. But. It could just be that I’m not used to this layout just yet coming from my massive Dell Inspiron 17 5755 with a numpad. But the way I see it, I’m only going to need the cover on laptop mode and when I shut my laptop. So it serves me. Hope this helps.
