I was looking for a thin bookcase envelope which simultaneously protects the rear glass (front I have a thick glass sheet) and still looks good. My search criteria has it totally fulfilled and the viewing window also serves its purpose. The good thing about the Sony product is that it is compatible with the docking station and all major entrances are accessible. So I can charge the phone with a closed envelope. The adhesive surface holds the phone securely super and thus the design of mobile phones is coming better advantage because there is no bracket obscured the corners or edges. (Holds even despite foil back) One point deduction is available for the push button. Magnetic closure would have been much better !! But you get used to it and so bad it does not look well. All in all, I'm so far after one week totally happy with it and would recommend to anyone who sees the positive side of the envelope and can forgive small mistakes.
