I purchased this product in order to be able to read in bed (without disturbing my wife). On this point, the object is perfect. What I regret is the usability and quality of materials. Indeed, on some books, the clip does not hold and at the slightest movement, light flickers. In addition, the "neck" of the lamp is not sufficiently hard and tends to bend .. By cons, in stationary use (on partitions over a laptop keyboard, etc.), it should be the perfect case.
