Since I like to read in bed at night without my husband störenzu, I looked for my ebook reader (Kindle) purchased the reading lamp. It is really very easy and complained the ebook reader hardly. The light illuminates everything sufficient (I have the lamp attached to the upper left corner). At first I had only disturbed that the light reflected on the frame and thus hidden something, but if you change the position of the lamp and she turns slightly to side, this shortcoming can be easily rectified. All in all a great lamp incl. The benefit of ordinary AAA battery.
