I purchased this light for use with my Kindle and have been extremely pleased.  The two-way switch offering using of one or both bulbs give good light control for varying reading areas.  The clip is rather thick and heavy, so this light does not work well on a paperback.  The clip strength is firm, so I don't have a problem with it slipping when clipped on my Kindle.  The light and cable fold down to the side for travel/storage; however, the bulk of the clip still makes a thick package.  I cannot fault the construction of the clip as it holds firmly and is not flimsy.  I would buy it again.
