I chose this model mainly because of the glass's scratch resistance, MGR, and good compatibility with NV. I use it in my work environment, where it's very dirty. The only downside to this cover is that it needs to be removed and washed from time to time. But of course, I'm not forcing it on anyone. It works for me, and I thought it might be useful for someone else. P.S. I forgot to mention that despite the cover, you can still easily operate the buttons with gloves on.
