The display is quite good: it is sharp and crisp. I use it for graphs so I'm only using its primary colors. I do not use it for photos or otherwise mixing colors so I have no opinion on that. The little feet work well.
It is a bit regrettable that the USB port is at the edge because my connector sticks out - but I can hardly complain about that because I am too lazy to use the power connector at the back.
My other complaint is that refreshing takes longer than I had anticipated. It is mentioned on the product page, but 20+ seconds is a long time when I'm looking at the inky frame waiting for the blinking to stop. This is a bit unfortunate because it draws my eye when it starts to blink.
