To be honest I was apprehensive on how this might work but it does. I can clip it on my computer or even stand it next to the computer. The 3 levels of light make it easy to get the right amount of light for what I need it. Works well with an e-reader or tablet too. It an be adjusted. It is easy to charge and it comes with everything so it also works well when traveling. I am thoroughly pleased with it and the price cannot be beat. Would definitely recommend this product.
