A:Answer In the sessions that I've used the pencil, it works smoothly and without complaint. My only issue with the glass is that it's almost too slick/smooth. It doesn't feel like writing on paper and is a noticeable change for me, but I'm sure I'll get used to it. I had the hdx cover first and it felt more like writing on paper to me, but it was misapplied and had micro bubbles everywhere. Kiddos to Best Buy for the replacement with glass when they had no more hdxin the store (they installed the protectors).
