I'm interested in getting one of these for the 7520 but the fit and function of the case/clip is a major thing for me. I use the stock clip with a few pieces of eGrips (none on the sides) on my unit and it's working for now. I really want improved grip, like what I had when I did have eGrips on the sides.. or better, but I can't sacrifice an easy to use belt clip to get that. Also the screen protector worries me although I could leave it off. I love the clarity of the screen and would only use the protector if it remained at the near perfect level it is now.
