Regarding my trade request and there is 6 out of 5 stars I have to put to the service. While online, no human contact, but a simplicity! Refunded or exchanged ... Remained to print out the T back (and their dependents) and wait for the delivery of the new ... Phillips regarding this post, are even offering "low end", no complaints, SD card reader, USB and auxiliary ... whaaa, it changes your life ;-)
