At first glance, it is: the dock is well packed, with two options "with or without shell" to ask the Z2. It looks exactly like the original, the only significant difference: the smartphone "hang" a little when the positioning is not as easy as sweats dk36. I use both Sony dock in the room, Kosee dock in the lounge. After a month, ottoman, although it recognizes my phone is on the dock, but not load. No problem with the Sony dock however. So for Kosee trash. Foreseeing I had taken two, we will see how long the 2nd stands.
