Unsuitable for PDF files

I have this nice gadget is actually brought it to my PDF files sometimes at night to be able to read in bed by the university. Unfortunately, I realized that in this case some restrictions on the representations of PDF apply and the device is suitable only conditionally.

1. Too small representation of the pages
Although you can adjust the magnification level by pressing a key, but this is true then only for this page, and you have my "back" button back to its original size in order to turn the pages.

2. If you want to solve the problem of 1st with the "Enlarge the font size", you can forget the pictures, because it is torn apart because of vergößerten letters. Tabular presentations are a horror so.

3. Loud buttons
If my girlfriend is in the evening in bed beside me, it is extremely annoying when I have to turn over each page with a loud "click".

However, books can be read and write quite well in the epub format. So if you value on reading eBooks pure, is hiermimt very well served. However, if you want to read PDF files / scripts from the uni so should can lassen.Da fingers thereof unfortunately the nice color screen save anything. Too bad, so going back now.
