I have bought this card envelope and was unfortunately very disappointed: On the one hand you have to purely Quest's the SD card into a little too small indentations to keep them safe in it and, above all, after only a couple of hours equal to the upper part of the cover-energized! ! It may of course be that I had bad luck and a Case've caught that from the outset had a manufacturing defect, but on the actual blue Case the Silberen outer shell is simply glued only with a thick adhesive tape, which does not keep very long ... (So I guess that probably can happen frequently during the processing way ...)
