watch out:
According to
this test the Aluratec is using LCD screen technology, instead of eInk (like most ereaders, also your dying coolER).
This makes a big difference in appearence of the text and the battery won't last long.
Unless you know, that you want exactly this (and have good reasons), I would try to get something else. This thing is really outdated.
Which are the other ereaders being offered in this webshop?
