Given all the positive reviews, I ordered two of these so that I have one at work as well as home. The box looks professional with a nice clean design. Inside is the dock, an adapter for use when the phone is in a cover, and a decent looking USB cable.
The only clue that this is not an official Sony dock is the lack of the "SONY" logo; otherwise you might think this is an official dock. The connector for the phone is of a good quality and the phone fits nicely into the dock. If you use the "Sony Connect" app to run actions when the device state changes, then it will recognise the dock and run any docked/undocked actions that you set up.
Overall this is an accessory that someone has obviously put some thought into. You won't be disappointed.
