My copy works but still very good and I am happy that I have made the risk.
Light intensity and light cones are ideal for me and I can finally use at any time of my Kindle.
One can also use the lamp independently of the Kindle otherwise; it stops at every book cover, can be plugged into a notebook. It is firm on flat surfaces, illuminated there a limited circle.
The casing meets the safety function on the go - especially the unit can not slip out even if the locking latch is open. The material of the shell feels for leatherette quite pleasant and is good overall processed.
