Most negative reviews do not refer to the map itself (with everything that is fine), but to incompatibilities with older card readers, digital cameras, etc. Who read (or google) can, is difficult to have an advantage. This is a HC card and which is recognized, in fact, not based on earlier models. But for that, the card can not. In my E51 it works beautifully, and as the current 1000in1 Hama card reader has thus (for firmware update) no problems. So if even a new format, please inform in advance if there is a firmware update for the old home appliance. Otherwise one takes hold on older microSD solutions back (which are in this size but much more expensive). I'm waiting for the mass market launch of the 8 or 16 GB microSD, ran in the tests without problems. Beeen E51
