The Lumia 1520 is pleasantly thin for its size and an absolute flatterer. That's why I was looking for a protective sheath that is not too much brushing and feel, receives the material sense. This is given quite well with the protective sleeve CP-623. The material feels -for me- very similar to this great, difficult to describe feeling somewhere between ceramics and plastics. The fit is good, fits like a glove, cut out all the holes correctly. The front, the "lid" is a rubber mat (in the white version is the rubber mat light gray), the interior a "velvety" surface has to conserve the display. At the same time you can use the cover folded as a stand. Power in practice very well. But I could imagine that the rubber cover which carries Verschleissspuren with frequent folding as stand you. The velvety surface on the inside is probably stuck to the rubber, a few mote large particles dissolve in daily use ever and are then when you open the display, you can blow away or wipe hauchzart with a soft cloth. Perhaps there the well over time. These last two points and the high price of about 20 euros have ultimately led me to "only" to give four stars. Nevertheless, it's a good shell, the well passes the feel and the look of the Lumia 1520 outwardly. Whether the case for cordless charging is fit, I have not tried it yet. The Fatboy charging pillow but has already loaded on his sleigh of Santa Claus, as my wife has assured several times on request :) Update 5/17/2014: Today my smartphone from 50cm height has dropped to the (concrete) floor. The smartphone hats (probably-hopefully) survive, the envelope is a corner chipped so that the sheath no longer usable. The internal flow from the lid has booze / residues left on the display until the end, when it was closed. Conclusion: With the function and feel I was happy with the CP-623, but the quality of materials / processing for this high price - absolutely inadequate.
