This is a good product. My wife ordered this first and after borrowing hers, I decided to get one for myself. I like the option of using one LED or two, depending on the level of light I need at the time. I do find myself re-positioning it from the left page to the right, but it's a quick and easy adjustment. The flexible arm is long enough to put the light right where I want it and stays in position well. I'm on my third book with it and have no regrets.
