I bought this after staying in a hotel room that had such poor lighting I was struggling to read my Kindle. I have used it many times at home when I want to read in bed but I don't want to keep my husband awake with the light on. It is perfect for the job. It is light - i don't actually notice the additional weight - and is bright enough to read without additional lighting. The light just falls on the kindle and doesn't light the rest of the room. It is easy to attach and has a firm clip so it doesn't move around. No complaints at all - it is definitely worth the money.
