Everything works, did not expect that a large sd card, thought micro, but a larger stronger hold, easier to solder, if the connector broke. Sd in the container, also good. The screen and sd are not connected-separate devices, which is convenient. It went as usual. The screen with a protective film is clean when removed. Tracked.
