The product does not work properly (screen freeze, SD card reader was not working). After contact with the seller (in Germany), apart from "we send our engineer" or "itemize specifically malfunctions" ... (while I had detailed the problems), I did not receive a valid response the seller. Worse, I looked more closely produced and I realized that the SD card reader was mounted upside down !!! I took pictures that I sent to the seller ... and still no answer! Yes, a one: asking me to cancel my application for "A to Z Guarantee" on Amazon, because it made them wrong !! I'm not at all satisfied with this seller !!! Or this. Stay away.
