Negatives:
The shipping time. They said yes, that it would take about four weeks (20 working days). In the end I had this card roughly ordered in mid-November 2014, and finally was able to take receipt of the end of January 2015; these were then so 8-10 weeks (have the exact date is not in my head).
In December, I had the company asked if there was a problem. They answered me kindly that they had no influence on the customs. Use the tracking number I was finally able to confirm that the package had to wait almost over in a city in China on his trip to Germany all the time. No matter whom you may blame additional four week wait is so inexcusable.
One star for the price, drastic deduction for the duration.
