The device is called Dogee T20 Ultra 12", I bought it from a local vendor for ca. 230 euro to avoid dealing with a Chinese vendor. Works without any problems and the battery lasts for many days with my usage pattern (that is only reading ca. an hour a day).
Edit: it looks like the TCL option the other person mentioned is better because of screen glare (I use mine indoors only but probably it would get uncomfortable in full sunlight).
But it seems something one would better test in person especially regarding the contrast/crispness of text hence my question how it works in the 11 model.
It's really just an Android tablet with some hardware and software that's there to facilitate reading and reduced eye strain. It's nothing entirely revolutionary but I find the price point to be the feature I like the most. Having spent $1000s on Galaxy Tabs over the years it's amazing the value for money the 11 model is.
