I have this reading lamp ordered due to the low price and I am very pleasantly surprised. The lamp is shaped like an oversized paper clip, so you can they cling perfectly to the spine of a book. When you have to Kindle the lamp easily between Kindle and pocket insert, otherwise the lamp could not be attached to the Kindle. The lamp is made of a rubber-like material that is apparently inside metal reinforced. Therefore, the lamp can be bent so that it has a great, individually adjusted illumination. The Kindle is perfectly lit and it also displays nothing on the screen. I can about the longevity of course say anything yet, but overall I am very satisfied and pleasantly surprised.
