I love to read, but my bedroom is far away from the only window in my 420-square-foot apartment so I always needed to use the wall-mounted light to read by day or night. After being here for over five years I felt it was about time to invest in a book-light. I have had them in the past but forget why they didn't seem to work out. I looked this one over and decided it looked like it was small, lightweight, easy to use, and in my favorite color (purple) at a really decent price. When it arrived I clipped it to the book I was reading, The Executioner's Song (also ordered from Amazon) and tried it out. It was PERFECT! The only time I may have problems is when I am down to the last few pages since I did clip it onto quite a few pages which I will not be able to do once I am down to only that many pages to read. Still, it is certainly nice that when I am through reading for the night I can just turn off the book-light rather than having to get off my bed, walk around to where the wall switch is to turn off the room light, and then return to my bed. The light comes with the option to use two lights, or just one, and so far I have used both lights so I have to push the button twice to turn it off, but that is no problem. I also have a good supply of AAA's already so when I need to replace the batteries I can do so right away. I can easily adjust the flexible neck to aim the light where I need it, or raise it up high enough to fully illuminate both pages at once. If there is a con to this product, I have not yet found it.
