The cover fits almost perfectly and can be with me and not moving, the camera alone already prevents movement of the cover, I welcome that the cover weakens the strong bulge of the camera. Negative are the side mount, annoy quite strong when you hold the 1020 in the hand, because they are narrow ridges and press into their own hands, the longer surfing itself made the unpleasantly noticeable, and they are also quite flexible and give a creaking after if you touch the unit at the top or bottom.
The real object of the cover, loading, works perfectly, I invite with this pad: PSC = 1, which I bought in July for my Nexus 4 (with which it unfortunately did not work.). You have the 1020, although halfway just put on the pad, but this was also the NEXUS and the Lumia 920 otherwise.
Conclusion: Works very well, is not bulky in your pocket and evaluate the unit visually. When ergonomics and choice of materials Nokia has resorted but next to it, therefore only 3 Starne.
