the toilet DT-900 is a stylish and in my eyes very quality product and work with my Lumia 920 without problems. The product has a high-quality plastic surface and it was a very nice soft Kable used.
The power supply could be less! According to other reviews I have expected a much larger power supply. So that everyone can get an idea itself, I have an idea of the power supply uploaded with Nokia Lumia 920 and its power supply.
Best regards from a satisfied customer!
