Meanwhile, I have the dock about 3 weeks and have to say it certainly was not a bad buy. The matte, slightly roughened surface has a pleasant feel. A removable insert can also shop for in a protective case, with exposed contact of course. Charging is my feeling apace. In about 2 hours a Sony Z1 is full again. In reviews of the charging cables of the same company it was more that there is no reverse polarity protection. I could not find here. If the phone is in the natural position is brought (face to the user), nothing happens. The other way around, however, I will not try ;-))) Why only 4 points? When I bought the dock, was still of a high-speed data transfer talk. That cost me some time with trial and error and research on the Internet. When something and at non-compliance with specifications I'm something special. Meanwhile, in the product description of no more talk and could also give 5 stars.
