I use the lamp for my Kindle and can thus illuminate the side well. I think the brightness and pleasant through the flexible arm lamp lighting can be well positioned. That the lamp is powered by a separate battery, I like that, because so my Kindle battery is not claimed by the lamp. The delivery time is quite long - since I have not found at the given tracking number the program, I have contacted the seller. There I was offered a faster delivery and resend. Since the lamp the next day came, this was not necessary - the service from the seller I think in any case great.
