Dimensions of the sleeve fit well with those of the phone. When attaching the envelope a little force has to be expended. However, she sits for then very good. Cutouts for the connectors and buttons are in the right place but must first be cut away (ie, the shell comes with implied contours to the appropriate connector and switch positions) .Nachteil: one must first cut the recesses free. Advantage: You can, if you like, the switch for protection against dirt, even under the silicone cover left)
