“Very nice display and the 13" size is impressive. Used the same https://github.com/fatihak/InkyPi build mentioned by someone else in the reviews and got it to work with relatively few issues. The refresh speed is much better than previous Inky Impressions, but still slow enough that it would suit something you want updated every 5 minutes, not 30 seconds.
Picture quality is excellent, including full colour pictures. You do need good lighting to make the most of the screen.
It makes really quiet clicking noises when redrawing the screen (apparently normal for this screen based on some posts I found) so I would not have it in the bedroom if noise bothers you.
It fits well in a standard A4 picture frame, but the screen itself is smaller than A4 so you will need to mask small parts of the device if you want to only see the screen through the frame”
