Super small lamp with a very long power supply wire, which suits me because it allows me to connect it to the other side of the sofa, exactly what I wanted. The clip is sturdy and holds up well it is large enough to fix the back of my couch (we do not have to fix it on a thin tablet, what). She is very bright, I expected a softer light. It should not be a headache, but it has the merit of very illuminate, then. It is easy to steer and also does not fall, the head is light so do not tilt alone. The switch is close to the clamp, which allows to reach easily.
In short, (too) many words to simply say that it is perfect! :)
