My favourite thing about the Xperia Z2 is how 'well rounded' the device is. Nice design, nice camera, nice specs and other handy (and not gimmicky) features such as water and dust proofing. If one day Apple decided to make Android device, I believe they would made something similar to the Xperia Z2.
And my favourite thing about Dbrand is how they cut every skins so precisely. I couldn't believe they mass-produced this skins because how precise the cutting is. I wish they were more popular so we could say goodbye to those crappy 10$ chinese plastic case
