This lamp gets an A+ from me. It is compact, bright and is such an improvement over those large, round fluorescent lights. I am legally blind but can still read and write as long as I have a bright light with some magnification. The Pro Flex is the best I have found. The stable stand and the strength of the clamps are perfect. This is a no-battery lamp with a lot of LED power around the magnifier lens. I can use it as a desk lamp or off. I would like an option to reduce the output of light, because sometimes if I look at an object under the magnification lens and it is a bit strong. If the lens was a little large an rectangle it would really be perfect.
