The shell makes a good, sophisticated impression. It fits very well in place of the back shell and it also does not contribute to fat on. The Grade 4 acts as a leaner from the good old days for the calendar leather jacket inside pocket. But why now just three points. Samsung currently advertises like a champ for the wireless charging and then brings out that does not support this a shell. Not only that, she has contacts to the NFC allow. But because she has two contacts which for a score of 4 Qi charging receivers are required. So the shell brings the ability not only failed but with a built also the possibility to retrofit otherwise. For those who can do without a beautiful Qi sleeve but in my eyes simply not suitable for the year 2015.
