The original cover of Kindle was simply too expensive. For this reason, I have long wanted to find something that is inexpensive and practical. With this article, the consistently got 5 stars, I've found the right one for my Kindle 4. The shell makes a good and stable impression and the LED lamp is prima positioned. It lights up the screen completely and is powered by a button battery in 2032. This holds generally 2 years and the battery in the Kindle will not be affected. One can read just fine and fatigue really in the dark. It is important that the magnetic lock locks the left cover well and the cover can be folded back. So you can read with the right hand alone and does not need, as in other cases, even the left hand to hold the lid like a book. All the keys are not limited fine to use. I am completely satisfied because of the value for money you get exactly what you need for protection for the Kindle and if it should be necessary is to read with the LED lights in order. From me a crystal clear buy recommendation !!!!!!!!!!!!!!!!!!!!!!!
