After a long search and reading, I decided for this cover, these are just here include contacts for the QI Laden. Most cases prevent loading or it is loaded only with lower performance.
It is also very slim with the replacement of the complete back and I feel the back as well as a significantly more stringent than the original.
The display of the clock and the other Watch Faces are quite succeeded. I also covered the display with the Base Case glass slide. For me, a very good combination.
