Nice device, thin and light, the buttons for page turning are noticeable when clicked, I would have liked them to be a bit quieter. One "bad" thing about the device is that because it has colors, the screen does not have high contrast and with the frontlight off, the screen is not very clear without sufficient ambient lighting. For me, who likes to read at night with a small bedside lamp (I didn't expect such a difference compared to a "plain" eink screen), I need the frontlight on, resulting in higher battery consumption (in the photos the device appears inactive, with an open book without the frontlight and with the frontlight on at 100 in warm tone). Otherwise, it is a very good device and the colors are convenient for notes and files with colored images. Also, koreader installs very easily as an app and makes the device more responsive when turning pages. It's also nice that it has a media player for audiobooks and music, but you definitely need Bluetooth headphones to use them.

The colors it advertises are somewhat faded, almost black and white. It is very slow and has many functions that it cannot actually support. It is not user-friendly for reading as it is extremely small and you can't hold it properly. Also, some file types, e.g. pdf, are not easily readable as it constantly jumps to the beginning and changes the layout. When you want to make notes, underline, etc., it is a real hassle to mark what you want, and if you make the mistake of using a pencil instead of a highlighter, it doesn't add the underlined text to the notes list. In general, very difficult to use and therefore very expensive.
