The QI-cover was packaged well and, as always, comes from Amazon quickly. It fits 100% on my Lumia and makes it really only barely noticeable thicker and heavier. What's getting used to: The back is now slightly curved, so that the Lumia on the table or a charging station rotates like a spinning top. To my taste would have preferred the entire shell this one millimeter can be thicker, but just plan. The wireless charging in conjunction with the Zens ZESC02B / 00 but works perfectly, so I am, except for the one point deduction completely satisfied because of the curvature.
