I have my Smart Cover now more than a year, the handling of installing the IPad works reliably. Also, the switching on and off worked fine until recently, when I closed the cover or opened. After just over a month from the frayed microfibre cover the inside to the outside edges. At first I did the overhanging fringe removed with nail scissors, now I have a lot to do there. The outside dirty unfortunately rapidly through the land to which you put the cover. Use a slightly damp microfibre cloth I could remove the traces of dirt from the outside well. What's much more annoying is that the inner surface of the cover is very dirty and is not cleaned, although I have visible dirt on the table always removed. But even with an inner cover angeschmuddelten I might still be alive. Most annoying that the outer edges of the cover and loosen the PU outer shell disengages from the microfiber inside. In addition, the automatic locking and the awakening of the iPad Smart Cover by no longer works reliably. Although I have set these features of Smart Covers in the settings, I have to turn on the iPad about every 6th time, although I opened the cover. Priced at 39.00 this is decided too bad. Therefore, only 2 stars! Apple BT-MD306 Polyurethane Smart Cover for Apple iPad Dark Grey
