Full anticipation I opened the Amazon package today. Therein lay the disappointment: original package had been opened and resealed with tape. In the OVP then the device - Display scratched, fingerprints on it, scratched frame. For even more detailed evaluation and testing revealed that all contacts of the Micro-USB cable from the cable had broken away Kafz and thus a power supply was not possible. Also turning nil (battery was probably discharged). Manual was missing, no micro SD card here. Thus, I was fighting with the CM at least spared.
Immediately returned! Something I do not know of purchases via Amazon!
