I since ca. 1 month use the shell already and am thrilled properly. I wanted from the beginning to have a case that can prevent the corners of the Kindle good, so if I the thing falls out of his hand, nichtt breaks. The shell protects the corners perfectly unlike some other cover. Furthermore, the "auto on / off" function works absolutely reliable - because pressing the power button has completely unnecessary. The "holding tongue" is a non-plus-ultra as pain nor the wrists when "upside down" reading. And at the table or on a plane, the "enable" "state function" of the envelope.
